Directed by: Gerald Thomas

Other mistake: Mick the orderly is Irish throughout the film, but when Nurse Dawson bumps into him and says, "You clumsy oaf," Mick's reply, "Look who's talking," is said in a London accent.
Continuity mistake: When we first see the Colonel reading a newspaper the headline on the page he is reading starts with the word "Birmingham", but when the camera angle changes it reads "Fontwell Park".
The Colonel: Come come, Matron. Surely you've seen a temperature taken like this before?
Matron: Yes Colonel. But never with a daffodil.
Trivia: After his performance as Charlie Sage in "Carry On Sergeant", Bob Monkhouse was asked by the producers to play a major role in this film. However, he turned down the film as he considered the salary being offered too low.
