Wholly Moses!

Wholly Moses! is a 1980 American Biblical spoof film written by Guy Thomas and directed by Gary Weis. Dudley Moore plays Old Testament-era idol maker Herschel, whose life and adventures seem to parallel that of the more famous Moses, all the while being misled to think he is the prophet of God. The film also stars Laraine Newman, James Coco, Paul Sand, Jack Gilford, Dom DeLuise, John Houseman, Madeline Kahn, David Lander, Richard Pryor, and John Ritter.
