Martin Compston may be best known as the dogged DS Steve Arnott in Line of Duty, but his path to television fame started on football pitches rather than soundstages. Born in Greenock on 8 May 1984, Compston had a brief professional football career before an injury rerouted him toward acting. In the years since, he has become one of Scotland’s most recognisable faces on British television, with roles spanning crime drama, thrillers, and even travel presenting.
As of 2025, Compston continues to expand his on-screen repertoire. His latest project sees him swap the rain-soaked streets of Glasgow for the neon lights of the Las Vegas Strip.

Martin Compston’s Career: Line of Duty and Other TV Shows & Movies
What role did Martin Compston play in Line of Duty?
Martin Compston played Detective Sergeant Steve Arnott in the BBC police drama Line of Duty. He appeared in all six series of the show, which aired between 2012 and 2021. Arnott is a principled and physically capable officer within AC-12, the fictional anti-corruption unit. The role became the defining performance of Compston’s career and turned him into a household name across the United Kingdom. The show’s cultural impact was substantial, and Compston’s portrayal of Arnott is widely regarded as central to its success. Line of Duty remains available on BBC iPlayer.
What movies and TV shows has Martin Compston been in?
Beyond Line of Duty, Compston has built a varied filmography. His breakout film role came in 2002 when he starred in Ken Loach’s Sweet Sixteen, a critically acclaimed drama about a teenager in Greenock. He later appeared in The Nest, a BBC thriller about a couple who invite a mysterious teenager into their home, and Vigil, the submarine-based BBC crime drama. Other notable credits include Traces, a forensic crime drama on Alibi, and Our House, a psychological thriller based on the novel by Louise Candlish. Compston’s IMDb filmography lists dozens of additional credits across film and television, demonstrating a steady output since his debut.
Compston’s shift from football to acting was not gradual. He was scouted for Sweet Sixteen while still a teenager, after a teacher suggested he try out for the role. The film premiered at Cannes and launched his acting career almost immediately after his football stint at Greenock Morton ended. That early success meant Compston never had to work his way up through minor TV roles in the way many actors do.
What is Martin Compston’s New Series?
In 2025, Martin Compston presented Martin Compston: Living Las Vegas, a travel series broadcast on Channel 4. The show follows Compston as he explores the culture, entertainment, history, and everyday life of Las Vegas, stepping away from scripted drama to front a documentary-style travelogue. The series represents a notable departure from the tense crime dramas for which he is best known. The programme is available via Channel 4’s streaming service. As of early 2025, no new scripted acting roles have been officially announced, though Compston’s schedule beyond Living Las Vegas remains a topic of interest among fans.
While some online sources have speculated about additional 2025 projects—including a potential second series of The Rig—these claims are not consistently confirmed across reliable entertainment outlets. Compston’s confirmed upcoming work as of early 2025 consists primarily of Living Las Vegas. Readers should treat unverified reports about future roles with caution.
What is Martin Compston’s Net Worth?
Public estimates of Martin Compston’s net worth vary considerably. The most commonly repeated figure in online sources is approximately $5 million, or around £3.5 million. However, multiple outlets note that this figure is not officially verified and may be based on industry averages rather than disclosed financial information. Some sources place the figure lower, around the $1–2 million range. A report from The Mirror suggests that his Line of Duty salary “significantly contributed” to his overall earnings, while Daily Star describes his net worth as “impressive” but does not provide a definitive number. The absence of official disclosure means all figures remain speculative.
Readers searching for Compston’s net worth will encounter varying numbers: some sites claim $5 million, others suggest $1–2 million, and a few offer no figure at all. This inconsistency arises because Compston, like most UK actors, has not publicly disclosed his earnings. Any net worth figure should be treated as an estimate rather than a confirmed fact.
