Continuity mistake: In the scene just before Lance Barton gets crushed by a bus, they show the character of Keys, waiting nearby disguised as a homeless man, waiting for the accident to happen. However, there was no reason for him to disguise himself in the first place as nobody on earth could see him anyway. In all the other scenes, just before somebody dies, he wears the same clothes (his heavenly uniform.)
Continuity mistake: When Wellington's wife and his personal secretary are about to "Get it on" on the pool table there are two balls just to the left of the left corner pocket. As the scene changes there is only one ball, then as the scene goes back there are two balls again.
