Corrected entry: When Trevor went to the police station to report his/Ivan's car and they said it was listed as belonging to him, why did the policeman automatically leap to the conclusion that he was committing a crime? Surely a more obvious conclusion would be that he had some form of amnesia caused by the crash, and he was "remembering" his own car's number plate rather than the car that hit him.
Corrected entry: In the film Trevor was an insomniac, so I doubt he would be allowed to operate dangerous heavy machinery?
Corrected entry: In the scene where Trevor goes into the bathroom at the bar, he tries to get soap but the soap dispenser falls to the floor. When he turns around to look for something else to wash his hands with, you can see the soap dispenser still on the wall.
