Revealing mistake: When Hattie Jacques and Barbara Windsor see Madeline Smith about her baby, you can see that the 'baby' is an obvious doll.
Revealing mistake: When Sid James blows up the store room door, the dynamite explodes before he turns the handle on the detonator.
Continuity mistake: When Mr Bernard pulls Miss Banks' dress he throws it behind her. When she runs to her office she is holding the dress in her hand.
Mr. Tidey: Well, what's happened?
Matron: I'm afraid it was another false alarm, Mr Tidey. You may as well go back to work.
Mr. Tidey: Go back to work? It was due three weeks ago.
Mr. Tidey: Well I'm sorry but babies tend to arrive when they feel like it. There's nothing we can do about it.
Mr. Tidey: That's a fine state of affairs, innit eh? We'd soon be in a right old mess if we ran the railways like that.
Matron: I was under the impression that you did.
Trivia: When Sir Bernard is in his study, he reads "The Psychology of Jealousy". If you look, you can see the author is Ernest Steward, director of photography for this film.
