This comedy concentrates on the mishaps befalling bigoted Frenchman Louis DeFunes. While en route to his daughter's wedding, the outspoken DeFunes accidentally gets mixed up in an Arab nationalist uprising. Through a bizarre and nearly indescribable combination of events, the fiercely anti-Semitic DeFunes is forced to disguise himself as a Rabbi. The sociological statements in Mad Adventures of "Rabbi" Jacob, coscripted by director Gerard Oury, are pepped up with heavy slapstick. Initially titled The Adventures of Rabbi Jacob for its American release, this French film had the "Mad" tag attached when audiences evinced a lack of interest in what was perceived to be a religious picture.
