Other mistake: When Frank and the Ghost of Christmas Past are at the office Party where the younger Frank is still working, as they stand by the entrance door two women leaving move in closer to try and avoid bumping them - despite the fact that the Ghost said earlier they couldn't be seen or affect what's going on.

Directed by: Richard Donner
Starring: Bill Murray, John Glover, Karen Allen, John Forsythe
Continuity mistake: After Claire hits Frank in the head with the door, she kneels down to help him up, and she has no purse. In the next shot she has a brown purse in plain sight on her left shoulder.
Earl Cross: All day long, I listen to people give me excuses why they can't work... 'My back hurts, ' 'my legs ache, ' 'I'm only four!' The sooner he learns life isn't handed to him on a silver platter, the better.
Trivia: When Frank throws water on a waiter he thought was on fire, he apologizes and claims he thought the waiter was Richard Pryor. This is a reference to the time Richard Pryor, while doing cocaine, set himself on fire and ran down a busy street in L.A.
Question: When Frank travels into the future and sees an older Calvin sitting on the floor, Calvin glances up. Did Calvin see Frank?
Answer: It's a vision, not reality, so one could interpret it either way. I think it's more powerful if Calvin is seeing Frank, silently accusing him of being (at least partially) responsible for his (Calvin's) situation.
