In 1960, Thaw made his stage début in
A Shred of Evidence at the
Liverpool Playhouse and was awarded a contract with the theatre. His first film role was a bit part in
The Loneliness of the Long Distance Runner (1962) starring
Tom Courtenay and he also acted on stage opposite
Laurence Olivier in
Semi-Detached (1962). In 1963/64, he appeared in several episodes of the
BBC series
Z-Cars as a detective constable. Between 1964 and 1966, he starred in two series of the
ABC Weekend Television/
ITV production
Redcap, playing the hard-nosed military policeman Sergeant John Mann. He was also a guest star in an early episode of
The Avengers. In 1967 he appeared in
Bat Out of Hell and in the
Granada TV/ITV series
Inheritance, alongside
James Bolam and
Michael Goodliffe; TV plays including
The Talking Head, and episodes of series such as
Budgie, where he played against type as an effeminate failed playwright with a full beard and a Welsh accent. Thaw was cast in the police drama series
The Sweeney (1975–1978) alongside
Dennis Waterman and
Garfield Morgan, playing the hard-bitten, tough-talking
Flying Squad detective Jack Regan. It established him as a major star in the United Kingdom. He followed this with four series of the sitcom
Home to Roost (1985–1990), which co-starred
Reece Dinsdale, about a divorced father whose teenage son moves back in with him after choosing as a child to live with his mother. He had previously co-starred in another ITV sitcom,
Thick as Thieves (1974), with
Bob Hoskins. Thaw's role as
Detective Chief Inspector Endeavour Morse in
Inspector Morse (1987–93, with later specials until 2000), cemented his fame. Alongside his put-upon
Detective Sergeant Robert "Robbie" Lewis (
Kevin Whately), Morse became a high-profile character—"a cognitive curmudgeon with his love of classical music, his drinking, his classic Jaguar and spates of melancholy". According to
The Guardian, "Thaw was the definitive Morse, grumpy, crossword-fixated, drunk, slightly anti-feminist, and pedantic about grammar."
Inspector Morse became one of the UK's most popular TV series; at its peak in the mid-'90s, it was viewed by 18 million people, about one third of the British population. He won "Most Popular Actor" at the 1999
National Television Awards and won two
BAFTA awards for his role as Morse. Thaw is mainly known in the United States for
Inspector Morse, as well as for the BBC series
A Year in Provence (1993) with
Lindsay Duncan. Thaw subsequently played liberal working-class
Lancastrian barrister James Kavanagh in
Kavanagh QC (1995–99, and a special in 2001). Thaw appeared in a number of films for director
Richard Attenborough, including
Cry Freedom, in which he portrayed the conservative South African justice minister
Jimmy Kruger (receiving a BAFTA nomination for Best Supporting Actor), and
Chaplin, playing the English
music hall impresario
Fred Karno alongside
Robert Downey Jr. (Chaplin). Thaw also appeared in the TV adaptation of the
Michelle Magorian book
Goodnight Mister Tom (
Carlton Television/ITV). It won "Most Popular Drama" at the
National Television Awards, 1999. During the 1970s and 1980s, Thaw appeared in productions with the
Royal Shakespeare Company and the
National Theatre. Thaw was the subject of
