Time Lock is a 1957 British thriller film directed by Gerald Thomas. The film follows the attempt to rescue a six-year-old boy who is accidentally locked in the South York branch of the Crown Canada Bank vault, in Toronto. With less than 10 hours of oxygen remaining in the vault, it becomes a race to save the boy.

The film features a young, pre-James Bond Sean Connery. The boy is played by Vincent Winter and his parents are played by Lee Patterson and Betty McDowall.

Although set in Canada the film was shot in England.

Rogers called the film "a little gem" and said it resulted in the Woolf brothers offering Thomas The Vicious Circle.
