This film could have been titled “There Will Be Beef.”
Marty Feldman's "In God We Trust" makes two miscalculations which are fatal to most comedies.
His movie (1) acts as if it's automatically funny when large groups of people mill about acting weird, mugging at the camera, and being astonished at the wild and crazy things being done by the star comedian. And (2) Feldman falls for that ancient comic trap of sentimentalism, in which the comedian's romance with the girl in the plot gets serious and touching. What the heck: We might as well throw in (3), the belief that characters will seem funny if you give them funny names.
The movie itself is a broadside attack on televised evangelists, particularly the kind who promise quick results from God if you send in your cash donations fast. This is an old target, and Feldman contributes nothing original to the attack. His evangelist (Andy Kaufman) sounds like Billy Graham, but acts like the yahoos in electric suits who camp out on the double-digit UHF channels.
How does Marty Feldman's character gets involved in the world of televised evangelicals? Feldman plays the simple, unworldly Brother Ambrose, of the Monastery of St. Ambrose the Unlikely. The mortgage on the monastery is held by the Rev. Armageddon T. Thunderbird (Kaufman), and Feldman is sent out into the world to beg Thunderbird not to foreclose.
