Directed by: Robert Day
Starring: Peter Sellers, Bernard Cribbins, Wilfrid Hyde-White, David Lodge
Factual error: Lenny says that he has seen the film "danger within" which was released in 1959 but two way stretch was released in 1960 and in this film Lenny has been in prison for the last three years so he couldn't have seen danger within.
Factual error: The prison in this film, Huntleigh prison, can't be very secure as the hinges are on the inside of the cell doors and the front gate opens directly into the exercise yard.
Revealing mistake: When the prison van drives through the tunnel, then stops and reverses so the crooks can set up the road works, it's supposed to be driven by Wilfrid Hyde White. But it's obviously being driven by someone else, as the driver looks nothing like him.
The Rev Fowler: I'll remember you all tonight in my prayers, boys.
Dodger: We'll be lucky if he remembers us after the second pint.
