The character was originally played by Andrew Burt from 1972 to 1973 with a brief return in 1976, when the actor left for Italy to write a book. On his return in 1980 he was played by Clive Hornby. Hornby remained in the role until 2008 when he was forced to take a break from Emmerdale due to illness. His last on-screen appearance was on 21 February 2008, and his absence was explained by the character visiting his mother, Annie Sugden in Spain. Although Hornby was intended to return, he died from his illness in July 2008 without returning to the programme. Jack was written out following Hornby's death, dying off-screen of a heart attack in February 2009.
