Grosse Pointe Blank (1997)

Continuity mistake: In the scene where Blank gives Debi an aeroplane ride on his feet, he takes off his cap to lie on the bed. When he gets up to leave the cap appears in his hand without his ever retrieving it from the bedpost where he hung it.

Debi Newberry: You're a psychopath.
Martin Blank: No, no. Psychopaths kill for no reason. I kill for money. It's a job... That didn't come out right.

Trivia: In the convenience store shootout, there is a large cardboard cut-out of the Pulp Fiction characters in the background. Bruce Willis's head explodes.

Question: Grocer contacts the G-men to tell them that Blank is arriving by plane. Is that his own car he is driving around town, or are we to assume that he rented a car exactly like his own? If it is his car, how did it get there if he flew?
