Crooks in Cloisters is a 1964 British comedy film directed by Jeremy Summers and starring Ronald Fraser, Barbara Windsor, Bernard Cribbins and Melvyn Hayes.
After a few initial setbacks, they slowly adjust to their new contemplative life of tending animals and crops, surviving the added tribulations of visits by a group of tourists and two of the real monks who had been forced to sell the monastery after falling on hard times, including Brother Lucius.
Some of the material is obvious, certainly, and even ardent enthusiasts of broad farce would seldom find it screamingly funny; but on the other hand, like Jeremy Summers' first film, The Punch and Judy Man, it is done with an ingratiating geniality and quiet good humour, coupled with an absence of the chamber pot jokes usually associated with this type of comedy.
The emphasis is firmly on character as Ronald Fraser and his gang lie low in a monastery to throw the cops off their trail.
Bernard Cribbins is in fine fettle as one of Fraser's gormless colleagues and Barbara Windsor is funnier than the Carry Ons ever allowed her to be.
