God, the Devil and Bob (2000)

"One divine comedy. One helluva show."

God strikes a wager with the Devil: if just one person can convince him that the world is worth saving, he'll spare humanity from destruction, if not, God will scrap all of creation and start over. The Devil is allowed to choose the candidate, and true to form, he picks the least likely person to determine the fate of the world--self-centered, slow-witted Detroit autoworker Bob Alman, an icon of mediocrity. Reluctantly, Bob accepts God's challenge, and has to live a decent life with no hints from God and constant temptation from the Devil. Caught between the forces of divinity and deviance, with the weight of the world on his shoulders, there's nothing left to do but laugh.
