On Sunday nights John Simm is the most reassuring presence on ITV: Detective Superintendent Roy Grace, a Brighton detective who believes in evidence and in the team that gathers it. His next stage role is Ray in David Harrower’s Blackbird, a man who served a prison sentence for his relationship with a child and has been living under another name ever since, until she walks into his workplace as an adult and demands an account. Few actors move between those two men with so little visible strain, and the distance between them is the most useful way to read his whole career.

The split was there from the start. The role that made him famous, Sam Tyler in Life on Mars, is a modern Manchester detective knocked back into the policing of his own childhood, decent and appalled and slowly seduced by it. Russell T Davies then cast him as the Master in Doctor Who, and Simm played the Doctor’s oldest enemy as a grinning, giddy wrecker who seemed to enjoy every second of the damage. Viewers who trusted his face in one were unnerved by how easily it turned in the other.

John Ronald Simm arrived on 10 July 1970 in Leeds, the eldest of three children, and grew up moving around north-west England, through Blackpool, Burnley, Colne, Manchester and Nelson. Music came first. From the age of twelve he sang and played guitar alongside Ronald Simm, the Manchester musician he knew as his father, on the stages of working men’s clubs. A drama teacher at Edge End High School in Nelson, Brian Wellock, pushed him toward acting; a performing arts course at Blackpool and The Fylde College followed in 1986, with musicals at the town’s Grand Theatre that convinced him musicals were not for him. He played Billy Liar and Amadeus with an amateur company, then moved to London at nineteen to train at the Drama Centre, where the method was Stanislavski.

The early television was the usual apprenticeship: a debut in Rumpole of the Bailey in 1992, a psycho in The Bill, the lead in the BBC sitcom Men of the World. The first role people remember came in Cracker in 1995, as Bill Preece, a damaged teenager. He made his film debut in Boston Kickout and his stage debut in Simon Bent’s Goldhawk Road at the Bush Theatre. Jimmy McGovern then gave him the lead in The Lakes, and in 1999 he became the face of a generation of clubbers as Jip in Human Traffic, the same year he played Eddie in Michael Winterbottom’s Wonderland.

The first half of the 2000s fixed his screen persona. He was Raskolnikov in the BBC’s Crime and Punishment and Bernard Sumner of New Order in 24 Hour Party People, a part that suited a working guitarist. In Paul Abbott’s State of Play in 2003 he played Cal McCaffrey, a journalist whose loyalty to an old friend in Parliament keeps compromising the story. Life on Mars arrived in 2006 and earned him a BAFTA nomination for best actor; he did not win. On stage, Simon Bent’s version of Elling moved from the Bush to the West End and brought him an Olivier nomination. Then came the Master, across three episodes in 2007, the special The End of Time and a return in 2017.

The canonised version of Simm is the Life on Mars man, and that version flatters less than it seems. When the BBC carried that world into Ashes to Ashes, it went on without him, and the character who outlived the format was Philip Glenister’s Gene Hunt, the bully Sam Tyler had been written to argue with. His American ventures fared worse. Intruders, the BBC America thriller he shot in Vancouver, was cancelled after one season, and ABC’s The Catch, a Shondaland caper in which he went from recurring player to regular, was cancelled after its second. The record suggests a blunt reading: Simm’s range has depended on British institutions, the BBC drama department, ITV’s Sunday slot, the subsidised stages of Sheffield and Chichester, to be fully legible.

Inside those institutions the work has been consistently ambitious. He played Hamlet at the Sheffield Crucible in 2010, then Pinter again and again: Betrayal, The Hothouse opposite Simon Russell Beale, and Lenny in a 50th-anniversary The Homecoming for Jamie Lloyd. On screen there was the Sky thriller Mad Dogs with Glenister, Marc Warren and Max Beesley, a second BAFTA nomination for Exile opposite Jim Broadbent and Olivia Colman, Michael Winterbottom’s Everyday, filmed over five years, and the ITV manhunt thriller Prey, which won him a Royal Television Society North West award. Collateral cast him as a Labour MP opposite Carey Mulligan, and in 2019 he played Macbeth at Chichester.

Grace began in 2021, Russell Lewis adapting Peter James’s Brighton novels into feature-length cases, and it has become one of ITV’s dependable hits. The sixth series, four films that started on 29 March 2026, opened with close to six million viewers and ended with a kidnapping at Roy Grace’s wedding to Cleo Morey. ITV confirmed a seventh series on 22 April, with Richie Campbell and Zoë Tapper returning, and filming began days later. Alongside it Simm plays Gray Wright, a washed-up music producer and one of the sons of a murdered patriarch, in Chris Lang’s I, Jack Wright, which first ran on U&Alibi in 2025, reached BBC One this year and has a second series on the way. In 2024 he was Scrooge in Jack Thorne’s A Christmas Carol at the Old Vic.

The guitar never left. Through the 1990s and early 2000s he wrote for and played in the band Magic Alex, which supported Echo & the Bunnymen on two British tours; he played on Ian McCulloch’s Slideling, and in 2002 sang Joy Division’s “Digital” with New Order at Finsbury Park. He has been married since 2004 to the actress Kate Magowan, his partner on screen in 24 Hour Party People and Exile, and they have two children. In 2024 he took a DNA test for the ITV series DNA Journey with Glenister and learned that Ronald Simm was not his biological father. He let the episode air.

Blackbird runs at the Ustinov Studio of the Theatre Royal Bath from 4 February to 6 March 2027, directed by Matthew Dunster, and the seventh Grace is due on ITV next year. The order matters less than the pairing: the detective who restores order on Sunday night, and a man the play refuses to let anyone forgive.
