Crooks Anonymous is a 1962 British comedy film directed by Ken Annakin, and starring Leslie Phillips and Stanley Baxter and Julie Christie, in her film debut. It was written by Henry Blyth and Jack Davies.

Captain "Dandy Forsdyke" is a habitual criminal who cannot resist a tempting robbery. His gifts are for pickpocketing and safecracking. He never uses his real name, of which he's ashamed. However, he is engaged to Babette, a stripper who wants him to go straight before they marry. In love with Babette, he desperately wants to quit, but is always lured back into another crime by his associates. Babette comes across a society known as Crooks Anonymous which helps hardened thieves go straight. Founded by Mr Montague, and funded by a generous legacy, they have an excellent track record. Babette agrees to help them cure Forsdyke.

Forsdyke is picked up during a robbery by a Crooks Anonymous man, Brother Widdowes, who is disguised as a policeman, and taken to the Crooks Anonymous' headquarters. Confronted by Montague, Forsdyke admits that he wants to give up crime and marry Babette. They begin to interrogate him, and discover that he is a habitual liar, whose real name is Cox, who has never seen military service, despite his claim to be a decorated veteran.

Widdowes and Montague embark Forsdyke on a dose of punishment therapy and rehabilitation. They begin by locking him in a room filled with safes, which contain cigarettes, food, drink and a number of booby traps which make opening them a hazardous business. After a week of this torture, Forsdyke is beginning to crack. Nonetheless, he fails a test to see how much progress he has made, reverting to his old ways as soon as he is outside.

After a month of correctional therapy and reinforcement training, Forsdyke finally passes the test and is released into society. He moves into a house with Babette, gets a job working as Father Christmas in a department store and refuses an offer by one of his old pals to go back into criminality.

However, after consuming large amounts of alcohol at a Christmas party he passes out and finds himself alone in the department store, with £250,000 of takings near him in the safe. Forsdyke breaks in intending to steal the money, and then panicking at his relapse, calls Crooks Anonymous for help. They send their two top men, including Brother Widdowes, who also cave at the sight of the money. They in turn call for Senior Brother, who arrives with his Secretary.

Confronted with this unique opportunity, the five of them decide to steal the money and split it among themselves. They go to Forsdyke's house, only to be confronted by an outraged Babette, who demands they put the money back. Grudgingly they agree, as she threatens to call Scotland Yard and inform them of the burglary.

They successfully manage to return the money, unfortunately triggering an alarm which brings the night watchmen out. However, they all get safely away. Forsdyke marries Babette and as a sign of appreciation they make her a Guardian Angel of Crooks Anonymous, for keeping them all honest.
