Continuity mistake: During the car scene, when God makes it rain, Jerry's hair goes from being dry to wet, repeatedly, depending on the camera angle.
Continuity mistake: When Jerry Landers wakes up in the night and finds the note on his pillow, he is holding it in his left hand. The next close up shows two hands on the note and then back to one hand.
Continuity mistake: In the scene where Jerry (John Denver) tells his wife (Terri Garr) about the interview with God, she serves him a full bowl of chicken soup which she sets on the table. When he sits the first time, the soup is there, he gets up to pace and when he returns to the table, the bowl is gone. The next shot is over Jerry's shoulder and he eats 3 spoons of soup. The camera switches back to a front shot and the bowl is empty.
Suggested correction: The level of soup in the bowl is not displayed due to the angle. The bowl of soup does not disappear. Jerry sits in a different seat than where the soup is and then pulls the bowl over to his new seat.
Continuity mistake: In most scenes, Jerry's AMC Pacer has no vent window in front of his side window. When Jerry is pulled over by a police officer, his AMC Pacer has vent windows.
