Jack Elvyn Barrett (18 February 1910 – 22 May 1983) was a British actor on film, television and stage, best known for his roles as Smellie Ibbotson in The Dustbinmen and Hylda Baker's father in Not On Your Nellie.

[4][5][6] Following the war, he joined weekly repertory companies across England, working in places such as Birmingham,[7] Rugby,[7] Bexhill-on-Sea[8] and Hastings[9] in Sussex, Portsmouth in Hampshire,[10] Bournemouth in Dorset,[11] and Burnley in Lancashire.

[15] The Daily Mirror wrote in 1976 that Barrett, then aged 66, "has the sort of career that makes him the envy of many younger actors".

[19] In 1968, he played the lead role in a revival of D. H. Lawrence's play A Collier's Friday Night, with reviewers saying, "The director, Peter Gill, elicits admirable style and even ensemble from a first-rate cast including John Barrett as the collier, Anne Dyson as his wife, Victor Henry as the son, and Jenifer Armitage as Maggie.

... John Barrett is wonderfully solid and self-satisfied at the start as an innocent faced by capitalism; and in his final gritty resignation to his fate the actor never puts an eyelid wrong.
