《布朗神父》是由亚历克·吉尼斯,琼·格林伍德,彼得·芬奇,西塞尔·帕克,伯纳德·李,希德·詹姆斯主演的一部剧情片，Father Brown tries to transport a historically important cross to Rome engaging in battles of wits and faith with a thief and pursuing policeman. The thief, named Flambeau (Finch), is a master of disguise and is elusive, as Father Brown pursues him and tries to convince him to abandon his criminal career.　　During the making of the film, Alec Guinness was mistaken by a small boy for an actual priest. This episode appears to have played a part in Guinness's later conversion to Roman Catholicism.
