The Counterfeit Constable

A French rugby supporter (Robert Dhéry), in England for a match at Twickenham, is accidentally elbowed in the face and loses two teeth. He goes to the dentist who fits new teeth and tells him he musn't open his mouth for two hours, to allow the cement holding them to set properly. He starts to wait, and in the waiting room he sees the uniform of another patient, who's a policeman (Bernard Cribbins). He tries it on for fun, and while wearing it by sheer chance he saves Diana Dors, a movie star who lives next door. He is congratulated by police chiefs who take him for a true police officer. He can't tell them he isn't because he can't open his mouth and besides, he doesn't speak English. He becomes lost in London, and many misunderstandings and misadventures follow. And to make matters worse he needs to return home to France urgently as he is due to be married.

Diana Dors was then living in Los Angeles but returned to Europe to make the film.[2]

Location shooting took place around London. Interiors were shot at Shepperton Studios and the Billancourt Studios in Paris. The film's sets were designed by the art director Jean Mandaroux.

Although it is a French film, The Counterfeit Constable nevertheless carries all the hallmarks and shows the type of humour found in an Ealing comedy. This is probably because nearly half the cast were composed of British actors and the film was mostly set in London.
