with straight and comedy roles on stage, radio, film and television. His first broadcast was as a regular on the radio show Educating Archie, and this led to appearances in both the radio and television versions of Hancock's Half Hour. By the late 1950s, he regularly appeared on television: as Sean Connery's trainer in boxing drama Requiem for a Heavyweight (1957), with Charlie Drake in the sitcom Drake's Progress (BBC, 1957) and a title role in Three 'Tough' Guys (ITV, 1957), in which he played a bungling criminal. He also appeared in several episodes of Armchair Theatre. During the first of these, Underground (1958), one of the lead actors died during the live performance. He also had roles in The Avengers in addition to many ITC drama series including: William Tell, The Four Just Men, Sir Francis Drake, Danger Man and as a recurrent guest in The Saint, as in the second episode of the first season, "The Latin Touch" in 1962, depicting an Italian taxi driver. His cinema début was in Guy Hamilton's Manuela (1957), and he began a career of minor roles as sinister foreign agents, assisted by his premature baldness and facility with Eastern European accents. He appeared in The Roman Spring of Mrs. Stone (1961), the Hammer horror The Curse of the Werewolf (1961), Carry On Cleo (1964), Where Has Poor Mickey Gone? (Gerry Levy, 1964), and Help! (Richard Lester, 1965) and played leads in All the Way Up (James MacTaggart, 1970), The Chain (Jack Gold, 1984), The Dunera Boys (Ben Lewin, 1985) and Foreign Body (Ronald Neame, 1986). In 1965, Mitchell was cast in the role for which he became best known, as the Conservative-voting, bigoted cockney West Ham United supporter Alf Garnett in a play for the BBC Comedy Playhouse series, broadcast on 22 July 1965. This was the pilot edition of the long-running series Till Death Us Do Part, with Gretchen Franklin, Una Stubbs and Anthony Booth. The part of Mum, played by Franklin, was recast with Dandy Nichols in the role when the programme was commissioned as a series. Mitchell's real life persona was different from Alf Garnett, being Jewish, Labour-voting and a staunch supporter of Tottenham Hotspur. The show ran from 1966 to 1975, in seven series, making a total of 53 30-minute episodes. While the series aimed to satirise racism, it actually also gained the support of many bigoted racists
