Coldwater is arguably ITV’s first meaty thriller of the autumn season, and the channel are starting strong – having bagged Andrew Lincoln to lead the cast.

The British actor became famous playing Edgar ‘Egg’ Cook in the 90s zeitgeist drama This Life, before being lured to the States. After portraying the central character in The Walking Dead for more than a decade, he’s back. And he’s very welcome. But his new character couldn’t be any more different to his zombie-slaying alter-ego Rick Grimes.

In the ITV six-part series, Andrew portrays a father-of-two, who feels emasculated after failing to intervene in a violent incident at a London playground. As a result, he subsequently moves his family to the rural Scottish idyll of Coldwater. But he soon discovers that the fictional town is so full of dangerous secrets, he’ll wish he’d stayed in London…

Here’s everything you need to know about the cast of Coldwater on ITV, including who plays John’s sinister new neighbour. Don’t be surprised to see so many comedic actors in the line-up, either, this is a darkly comic thriller that will make you laugh, too.

Andrew Lincoln leads the cast of Coldwater on ITV as John

London-born Andrew Lincoln, 51, plays depressed dad John in Coldwater. ITV describe the character as as “middle-aged, with two young children”. He is “at a point in his life where he’s examining everything” and his ”alpha’ new neighbour doesn’t exactly help settle John’s mind.

Of course, actor Andrew should be very well known to TV viewers. In fact, Coldwater marks his long-awaited return to British TV after more than a decade in America filming The Walking Dead.

Having cut his teeth playing Egg in BBC drama This Life between 1996 and 1997, he went on to portray Simon Casey in the popular C4 drama Teacher.

Between 2005 and 2006, Andrew played university lecturer Robert Bridge in the supernatural series Afterlife. He starred opposite Lesley Sharp who played medium Alison Mundy. After portraying Edgar in the 2009 Tom Hardy version of Wuthering Heights, and Hugh Collinson in Strike Back, Andrew went on to win the life-changing role of Rick Grimes in Emmy-winning apocalyptic drama The Walking Dead.

He played the zombie-slayer between 2010 and 2022, and reprised the role in 2024’s spin-off The Walking Dead: The Ones Who Live. Andrew initially left Atlanta-filmed The Walking Dead to be closer to his family, who live in the UK. 

Film fans will know him from his roles in Love Actually, Human Traffic, Enduring Love, and Made in Dagenham.

Indira Varma plays John’s wife Fiona

Bath-born Indira Varma stars as John’s sexually-frustrated wife and famous chef Fiona – who sees through their new neighbour Tommy straight away.

The actress, 51, is perhaps most famous for playing ill-fated Ellaria Sand in Game of Thrones. Yep, she was the lover of Pedro Pascal’s character Prince Oberyn Martell. So, if you’re part of the (ever growing) population that adores him, you’ll probably be a bit jealous…

Indira is also known for portraying Niobe in the award-winning period drama Rome. She played the beautiful wife of Lucius Vorenus in the HBO series, which ran from 2005 to 2007. 

The actress has been on our screens for three decades, having made her very first TV appearance as Maya in the 1996 film Kama Sutra: A Tale of Love. It was quite the spicy leading role to mark her debut! 

Ewen Bremner portrays John’s neighbour Tommy

Scottish Ewen Bremner, 53, stars as John’s neighbour Tommy. Married to a vicar, and a bible group leader himself, he comes across as charming at first… But he’s hiding a rather sinister secret.

Trainspotting fans will know the Edinburgh-born actor best for his comedic turn as Spud in the 1996 film and its 2017 sequel.

He’s been in tonnes of other films, too, including Guy Richie’s Snatch, in which he played a street thug called Mullet. Movie fans might remember his roles in Pearl Harbor, Black Hawk Down, The Reckoning, Match Point, Snowpiercer, and Wonder Woman 1984.

He’s less frequently seen on TV, so his straight role in Coldwater is a pretty rare one. His very first small screen role was playing Jason in a 1990 episode of Taggart, and he went on to pop up in episodes of Screen Two, A Touch of Frost, Alleyn Mysteries, and The Bill.

Best known for his comedic roles, Ewen then appeared as Jockey in the sketch show Harry Enfield and Chums. Other notable TV roles in the 90s/00s included Michael Fry in The Secret World of Michael Fry, John Twain D’Wain in Langt fra Las Vegas, and Johnny in Coming Up.

He had a posh period in the 00s, too, when he played King James VI in the 2005 Helen Mirren series Elizabeth I. That year, Ewen also portrayed Sir James Melville in The Virgin Queen.

In 2015, Ewen portrayed Reverend Johnson in the British convict drama Banished, before playing Richard Topcliffe in Will. Most recently, he starred as Buttons in the comedy our Flag Means Death. It’s cancellation after two series was an unpopular move amongst fans.

Eve Myles stars as Tommy’s wife Rebecca

Welsh actress Eve Myles, 47, stars as Tommy’s vicar wife Rebecca – who doesn’t actually believe in God – in the cast of Coldwater. But we wouldn’t blame you for feeling a tad confused about the character. After all, Eve is currently playing a morally-ambigious – and super-rich – businesswoman called Fran in The Guest over on BBC One.

We know we’re in good hands with Eve, though, as she’s well known for her roles in thrillers, including Keeping Faith, Broadchurch, We Hunt Together, and Hijack.

Powys-born Eve has been on our screens since 1999, when she first popped up as Tracy in Hang the DJ. After small roles in TV series such as Nuts and Bolts, Tales from Pleasure Beach, and Colditz, Eve won the coveted role of Gwen Cooper in three episodes of Doctor Who. Her fans will know that she reprised the role in Torchwood, a spin-off of Doctor Who, between 2006 and 2011.

Other notable roles include Maggy in Little Dorrit, Ceri in Belonging, Sarah in Baker Boys, Frankie in Frankie Maddox, and Lauren Grey in You, Me & Them.

In 2008, Eve portrayed Claire Ripley in the brilliant Broadchurch, before going on to play Mrs Jenkins in Victoria, and Caitlin Henderson in Cold Feet.

She is arguably best known for leading the cast of Keeping Faith as Faith Howells, opposite her real life husband Bradley Freegard.

More recently, she’s played DS Lola Franks in the mostly underrated We Hunt Together, and Alice Sinclair in the thriller Hijack. Earlier this year, the mum-of-three portrayed DCI Jeanette Kilburn in The Crow Girl. Her character hunted for a killer targeting young men.

She’s been in tonnes of films, too, including To Provide All People, Eat Local, Under Milk Wood, and Soundproof.

Samuel Bottomley stars as Tommy and Rebecca’s son Cameron

Bradford-born Samuel Bottomley, 24, stars as Tommy and Rebecca’s 19-year-old son Cameron in the cast of Coldwater on ITV. The up-and-coming actor is perhaps best known for his roles in Ackley Bridge, Somewhere Boy, The Teacher, and Am I Being Unreasonable?

The actor has been on our screens since he was nine, when he starred in the award-winning film Tyrannosaur opposite Olivia Colman. He went on to play a young Thomas Cromwell in Wolf Hall, Brandon Kelleher in Rocket’s Island, George Quaintain in Jericho, and Denier in Kiss Me First.

Between 2017 and 2018, he portrayed Jordan in Ackley Bridge. Viewers were gutted when Samuel’s character Jordan Wilson left Ackley Bridge in emotional scenes. Jordan left Ackley Bridge High School behind when he accepted a place at art college, which meant moving away.

Samuel then went on to play Kyle in the first series of The Teacher in 2022 on Channel 5. He played school pupil Kyle, who accused his teacher (played by Sheridan Smith) of sexually assaulting him. That same year, he starred as Aaron in the highly-rated C5 series Somewhere Boy.

Most recently, Samuel played ‘Boy’ in the brilliant Daisy May Copper comedy Am I Being Unreasonable? His character kept popping up throughout series 1 and 2, and we eventually found out he’d witnessed a shocking murder.

He’s been in multiple films since his debut, including Private Peaceful, Ghost Stories, Get Duked!, and Everybody’s Talking About Jamie. This year, he plays Billy Boyd in the James Corden/James McAvoy movie California Schemin.

Jonathan Watson plays John’s therapist Williams

Glaswegian Jonathan Watson, 67, plays John’s therapist Williams in the cast of Coldwater. As it’s set in Glasgow, he would have felt right at home on set!

The actor is probably best known for his comedic roles in TV series such as Two Doors Down, and City Lights. He’s actually been on our screens for more than five decades, ever since he played Frank Garson in the 1970 The Wednesday Play. Subsequent early roles came in Dr. Finlay’s Casebook, and Cloud Howe.

Between 1984 and 1991, Jonathan portrayed Brian in the sitcom City Lights, before appearing in the sketch show Naked Video. The comedian and impressionist subsequently starred in football comedy Atletico Partick, and Rab C. Nesbitt. Those of you with children, or a penchant for kids’ shows, might recognise his voice as that of Humf in the 2007 animation of the same name.

Other notable roles include Frank in Brian Cox’s Bob Servant Independent, Clive Bagshawe in Fried, Sontaran Commander Stenck in Doctor Who, and Big Al McKee in Guilt.

Between 2016 and 2023, he became famous for portraying Colin in the sitcom Two Doors Down. At the same time, he continued to appear in the sketch show Only an Excuse? The Scottish comedy show airs every New Year’s Eve, and has done most years since 1995.

Most recently, Jonathan has popped up as Vince Whitby in Casualty, and Paul in The Diplomat.

Cast of Coldwater on ITV: Lois Chimimba stars as Catriona

Scottish actress Lois Chimimba plays Catriona in Coldwater. But she’s probably best known for her roles in the thrillers Vigil, Nightsleeper, and The One. You could say she’s developing a bit of a niche…

She made her small screen debut playing Beth Forbes in several episode of Holby City in 2014, before going on to play Karen in the Jodie Whitaker nursing drama Trust Me. After several years as a jobbing actress, Lois appeared as Catherine Streeter in A Discovery of Witches, before winning arguably her biggest role to date.

In 2021, she took on the role of Hannah Bailey in the Netflix psychological thriller The One. The series followed a DNA researcher who discovered a way to find the perfect partner, and subsequently created a bold new matchmaking service. But, of course, the fairytale turned to a nightmare when a man died.

That same year, Lois played Tara Kierly in Vigil series 1, and Carrie McAndrew in Shetland. As well as appearing in Sex Education! It was certainly a very busy year for Lois, as she also started playing Claire in the comedy drama The Outlaws, a role she returned to for series 2 in 2022.

Other significant roles include DC June Ayoade in the excellent true crime drama The Thief, His Wife and the Canoe, Amy in Still Up, and Erin Connolly in Nightsleeper. She’s lent her voice to several podcasts, too, including Doctor Who: Redacted, and The War Master.

Her film roles have included a nurse in the 2018 TV drama Care, Becks in Beep, and the main character of Lucy in the Frankenstein-esque 2.0 Lucy.

How old is the actress who plays Catriona?

Lois Chimimba is actually 34 years of age. This is a fair bit older than her character. In Coldwater, much is made of Catriona’s youth. We don’t want to reveal too much here, but the barmaid and shopworker is supposed to be 25, nine years younger than the actress who plays her. She mostly hands around with Tommy and Rebecca’s son Cameron, who is 19.

Catriona even makes jibes about John’s wife Fiona being “old”, and “looking good for her age”. In fact, Fiona is played by Indira Varma, who is 51 in real life. So only 16 years older than actress Lois. And, yes, she does look fantastic for ANY age!

The age discrepancy might be jarring for some viewers. In The Bay series 3, actor Nadeem Islam portrayed teenager Jamal Rahman. But he was actually 25 years in real life – quite a bit older than his character. And viewers were quick to point that out.

Greg Hemphill is Bobby

Actor Greg Hemphill, also from Glasgow, portrays Bobby in the Coldwater cast. Like his co-star Jonathan Watson, TV viewers might know him best for his comedic roles in the likes of Still Game.

In fact, he started his TV career in sketch shows, first appearing in the 1995/1996 Scottish comedy series Pulp Video as various characters. He went on to star in the 1999 to 2005 sketch show Chewin’ the Fat, with many of the same funny faces including Ford Kiernan.

Now 55, Greg is most famous for playing Victor McDade in the cult Scottish comedy Still Game between 2002 and 2019. Once again reuniting with his comedy partner Ford Kiernan. The pair played OAP’s Jack and Victor in the fictional area of Craiglang, Glasgow.

More recently, Greg has appeared in children’s TV show Olga Da Polga, voicing Mr Sawdust, and played Ade MacArthur in Hulu’s Dinosaur, and Head Guard Randy in Silo.

He even brushed shoulder with Ryan Reynolds and Hugh Jackman in Deadpool & Wolverine. Greg portrayed a seedy bartender in the 2024 Marvel film.

Abigail Lawrie stars as Moira-Jane in the cast of Coldwater on ITV

Aberdeen-born Abigail Lawrie, 28, stars as primary school teacher Moira-Jane, Tommy and Rebecca’s daughter, in the ITV thriller. She’s most famous for playing Anna Worth in the Prime Original drama Tin Star. 

Abigail portrayed the daughter of Tim Roth’s character Jack in three series of the popular drama, between 2017 and 2020. It was a huge role for the then 20 year old.

Her first ever TV role was in 2015, when she was 18. She starred as Krystal Weedon in the drama The Casual Vacancy, based on the novel of the same name by J.K. Rowling. In 2022, Abigail once again starred in one of Rowling’s adaptations, albeit one of her Robert Galbraith novels. She played Margot Bamborough in Strike: Troubled Blood.

A year later, the young actress won the leading role of Lana in the 2023 Paramount+ thriller No Escape. The whodunit followed the police investigation after a yacht was found adrift in the seas around Queensland stocked with plenty of food and everyone’s personal items but with nobody onboard.

Most recently, Abigail played Elspeth in one episode of Good Omens.

Coldwater cast on ITV: Sanjeev Kohli plays Malky

Although actor Sanjeev Kohli was born in London, they moved to Glasgow when he was a child and he subsequently went to the University of Glasgow. He plays Malky in the cast of the ITV drama Coldwater.

The 53-year-old is generally best known for his comedy roles in the likes of Still Game, and Fags, Mags and Bags, but he did recently pop up in the dark Netflix drama Dept. Q.

He’s been on our screens since 2001, when he played Jeggy 2 in the comedy Shredded Week, and went on to appear in Comedy Lab. But it was 2004 when he landed his first big role, playing Mr Kasmani in the children’s TV show Shoebox Zoo.

A year later, Sanjeev portrayed Surjit in Nitin Ganatra comedy Meet the Magoons, before going to play Mo Khan in Hope Springs opposite Strictly’s Alex Kingston. Other notable roles include Gupta in Angelos Epithemiou’s Moving On, Stan Clark in Avenue 5, and Dr Kamal in Magpie Murders, and Moonflower Murders.

Between 2002 and 2019, the actor starred as Navid Harrid in Still Game, opposite his Coldwater co-star Greg Hemphill. He’s also famous for playing Ramesh Majhu in podcast series Fags, Mags and Bags, and Amandeep Jandhu in Glasgow-based soap River City.

Sanjeev has also popped up in TV series such as Holby City, Fresh Meat, The IT Crowd, and Cold Feet. More recently, he played Doctor Sail in The Rig series 2, and Martin Fleming in Dept. Q. He also played Ned in the 2025 film Grow.

Gilly Gilchrist stars as Angus’ dad Nathan

Edinburgh-born Gilly Gilchrist, 63, stars as Angus’ dad Nathan in the cast of Coldwater on ITV. A jobbing actor across four decades, he’s perhaps best known for playing Billy Taylor in the soap Crossroads, a role he played between 2001 and 2002.

More recently, Gilly has played Martin Williams in Invasion, Jimmy McJagger in Rebus, and Constable Cunningham in Dept. Q. He’s also been in tonnes of films, including Gladiator, Rob Roy, Mercy Falls, Limbo, Outlaw/King, and Papillon.

Christopher Colquhoun stars as Jez

Sheffield-born Christopher Colquhoun, 55, plays Fiona’s “London friend” Jez in the cast of the ITV thriller. He’ll be familiar to Casualty viewers as registrar Simon Kaminski, a role he played from 2002 to 2004 (as well as popping up in Holby as the same character). 

Between 2009 and 2010, Christopher portrayed Matt Davis in Coronation Street. Matt was the wealthy manager of a Weatherfield cash and carry.

The actor went on to play Dr Anthony Carmichael in series 7 of Vera in 2017. That same year, he began portraying Agent Crown in the Prime Video series Absentia, a series about an FBI agent who must reclaim their life when they find themselves the prime suspect in a string of murders. Chris appeared in all three series, up until 2020 when the show came to an end.

More recently, Christopher starred as Edmund Lennox in Patience, Paul McGuire in The Sandman, Teddy Sloane in The Man Who Fell to Earth, and Roger in This Time with Alan Partridge.
