Martin Compston: Living Las Vegas – Everthing you need to know about the Line of Duty actor

Martin Compston: Living Las Vegas sees the Line of Duty star explore the city he now calls home, taking viewers behind the famous Strip to discover the people, places and experiences that make Las Vegas tick. Here’s everything you need to know about Martin Compston, his wife, his life in Las Vegas and how to watch his new Channel 4 series.

Martin Compston is best known to television viewers as Detective Inspector Steve Arnott in Line of Duty, but his latest TV role takes him a long way from the AC-12 interrogation rooms.

In Martin Compston: Living Las Vegas, the Scottish actor explores the city where he spends part of his life with his American wife, Tianna Chanel Flynn, and their young son.

The three-part Channel 4 documentary sees Compston attempt to understand Las Vegas from a different perspective, looking beyond the casinos, neon lights and tourist attractions to explore the communities, characters and experiences that make the city his adopted home.

The first episode airs on Channel 4 at 10pm on Wednesday 23 September 2026.

For viewers looking for where to watch Martin Compston: Living Las Vegas, Channel 4 is the home of the documentary.

What is Martin Compston: Living Las Vegas about?

The documentary follows Compston as he explores the city beyond its familiar image of casinos, luxury hotels and nightlife.

Although Las Vegas is home to more than two million people across the metropolitan area, it is often portrayed primarily as a tourist destination.

Compston’s connection is more personal. His wife Tianna is from Las Vegas, and the couple have a son growing up there. Compston has spent years dividing his time between Scotland and Nevada, but the programme sees him trying to develop a deeper understanding of the place and the people around him.

Radio Times describes Las Vegas as Compston’s home for part of the year, with the actor using the documentary to explore the city from a more local perspective.

Rather than simply ticking off the city’s most famous tourist attractions, the series takes him behind the scenes and introduces him to people who help make Las Vegas what it is.

What happens in episode 1?

The opening episode takes Compston into some of the more extravagant and unusual corners of Las Vegas.

He visits a $25,000 hotel suite with its own basketball court, before getting behind the scenes at the famous Bellagio fountains, where he spends time with the water maintenance team.

The Bellagio fountains are among Las Vegas’s best-known free attractions, and Compston gets an unusual look at what goes on behind the spectacular public show.

He also attends a wedding involving a British couple at the Little White Wedding Chapel, one of the city’s famous wedding venues.

The episode then takes a very different turn as Compston heads to the casino at the Palms and tries his luck at the tables. The programme’s gambling sequence sees him put a substantial amount of money at stake.

Who is Martin Compston?

Martin Compston is a Scottish actor from Greenock, best known internationally for playing DS Steve Arnott in the BBC crime drama Line of Duty.

The role made him one of the most recognisable faces on British television, with Compston starring alongside Vicky McClure and Adrian Dunbar as part of the show’s AC-12 team.

His other screen credits include The Nest, Traces, Our House, Vigil and The Rig, among other television and film projects.

Compston has also recently been discussing the return of Line of Duty. He has confirmed that the show’s seventh season is in production, with the new series bringing him back together with Vicky McClure and Adrian Dunbar.

How old is Martin Compston?

Martin Compston was born in 1984 in Greenock, Scotland.

He began his acting career as a teenager, making his film debut in Sweet Sixteen, the 2002 Ken Loach film.

His early performance established him as a significant young Scottish acting talent, before his career expanded into television and international productions.

Who is Martin Compston’s wife?

Martin Compston is married to Tianna Chanel Flynn, an American actress from Las Vegas.

The couple have a son and divide their time between Scotland and Las Vegas.

Tianna’s connection to the city is an important part of the story behind Martin Compston: Living Las Vegas. Compston is not simply visiting Las Vegas as a television presenter or tourist – it is a city closely connected to his family life.

Radio Times has previously reported that Compston lives between Scotland and Las Vegas with his wife and son.

Where does Martin Compston live?

Compston divides his time between Scotland and Las Vegas, where his wife is from and where the couple’s son is growing up.

That unusual split between his native Scotland and his adopted home in Nevada is central to the new Channel 4 documentary.

The programme effectively asks a question that Compston himself has been grappling with: what does it mean to call somewhere home when you have strong ties to two very different places?

What is Martin Compston famous for?

For many viewers, Martin Compston will always be associated with Steve Arnott in Line of Duty.

Arnott is an officer within AC-12, the anti-corruption unit at the centre of Jed Mercurio’s hugely successful BBC drama.

Compston has played the character since the show’s first series and is returning for Line of Duty season 7, which is expected to continue the story of AC-12. Recent comments from Compston indicate that the forthcoming season will bring the existing story arc towards a significant point.

However, Line of Duty is only one part of Compston’s career.

His first major film role came in Sweet Sixteen, while subsequent television work has included Monarch of the Glen, The Nest, Traces, Vigil and The Rig.

Martin Compston’s Las Vegas guide

One of the attractions of the Channel 4 series is that Compston is able to approach Las Vegas with both a visitor’s curiosity and a resident’s familiarity.

Among the places and experiences featured across the series are the Bellagio fountains, Las Vegas’s entertainment scene, the city’s Arts District and locations outside the main tourist areas.

In the second episode, Compston visits the Arts District with local chef James Trees, explores Sandy Valley Ranch with his wife Tianna and travels to the Grand Canyon, where he is guided by Sonia of the Hualapai Native American tribe.

The series therefore goes beyond the traditional Las Vegas checklist and looks at culture, food, outdoor experiences and the communities around the city.

Martin Compston: Living Las Vegas episode guide

Episode 1 – Wednesday 23 September

Compston begins his exploration with some of the more spectacular sides of Las Vegas.

He visits a $25,000 hotel suite featuring its own basketball court, goes behind the scenes at the Bellagio fountains, attends a British wedding at the Little White Wedding Chapel and visits the Palms casino.

Episode 2 – Wednesday 30 September

The second episode moves beyond the Strip.

Compston visits the Las Vegas Arts District with chef James Trees, heads to Sandy Valley Ranch with Tianna and reconnects with Scottish drag artist Lawrence Chaney.

He also travels to the Grand Canyon, where he learns more about the history and spiritual significance of the area from Sonia of the Hualapai Native American tribe.

Episode 3

A third episode completes Compston’s Las Vegas journey, continuing his exploration of the city and the wider region.

The three-part format allows the series to look beyond the headline attractions and examine what life in and around Las Vegas is like for the people who live there.

Is Martin Compston: Living Las Vegas worth watching?

For Line of Duty fans, the documentary offers a very different side of Compston from the intense Steve Arnott role.

Instead of police investigations and lengthy AC-12 interrogations, viewers get to see the actor exploring his adopted home, meeting locals and experiencing some of Las Vegas’s more unusual attractions.

The programme also offers a different perspective on a city that is often reduced to the Las Vegas Strip.

Compston’s personal connection gives the documentary an additional layer: this is a city where his wife grew up and where their son is being raised, rather than simply a destination he has travelled to for filming.
