Continuity mistake: In the movie's final moments when Tom Cruise is buying back all his household items, the lady in the cargo bay says "that's everything," except for the crystal egg she throws out into the yard for Tom to catch. You can clearly see many more items left in the truck. But when the truck pulls away seconds later, nothing is left in the cargo bay except our villain sitting on a chair. Where did everything else go?
Continuity mistake: When Tom Cruise is recruiting customers, he's smoking while sitting outside a hamburger stand talking to two guys. He snuffs out his cigarette in an ashtray (which already had another burning cigarette), but when the shot changes to a long view, his cigarette is back in his hand fully lighted.
Continuity mistake: In the scene where Jackie gives Joel Lana's phone number, Jackie writes the number along the length of the envelope. In the scene where Joel uses the number from the envelope, it is seen that the name and number are wrote along the width of the envelope.Also Jackie wrote the number on the back of the envelope and then (when Joel will use the number) the name and number are wrote on the other side of the envelope.
