Jack Smethurst made his film debut in 1958's Carry On Sergeant. This was followed by parts in the films Saturday Night and Sunday Morning, A Kind of Loving, Run with the Wind, Night After Night After Night, the big-screen version of Please Sir! and the ITV sitcom For the Love of Ada amongst others, before he landed the role for which he is best known – that of bigoted socialist and union leader, 'brother' Eddie Booth in Love Thy Neighbour. The programme ran for eight series between 1972 and 1976. During this run he also appeared in the 1974 film version of the sitcom Man About the House. He reprised his role as Eddie Booth for the 1979 sequel Love Thy Neighbour in Australia. After Love Thy Neighbour ended, his film appearances have been few and far between, but include Chariots of Fire, the John Goodman vehicle King Ralph and 1996's La Passione. He made several appearances as Davenport in Britain's longest-running television sitcomLast of the Summer Wine in 1997. He has played four different characters in Coronation Street: a brewery drayman in 1961, and in January 1967 Percy Bridge, who tried to con Elsie Tanner. Between 1980 and 1983, he occasionally appeared as Johnny Webb, one of the men on Eddie Yeats' bin round. In 2001, he returned for several months as Stan Wagstaff, a friend of Jimmy Kelly, who left his allotment to Jack Duckworth. Together with his brother Ernie, Stan let Jack in on Jimmy's big secret — he used his allotment shed to brew poteen. Smethurst also starred in Vince Powell’s seven-part BBC Radio 2 slice-of-life sitcom A Proper Charlie in 1984, as factory worker Charlie Garside.
