Other mistake: At the beginning of the cabbie scene when Phil attempts to free the car from the taxi the second time, he is driving forward and the taxi is being pushed backwards. However when Phil hits the brakes the cabbie lurches forward (towards his dashboard). As his car was going backwards, a sudden stop should have pushed him back into his seat rather than lurching him forward towards the dash.
Other mistake: During the scene where Phil and Claire break into the real estate office to look up the name of her past client, Claire says his name is Holbrooke Grant. She types that into the computer to search for it, but it's shown as Holbrooke, Grant. With the comma, that would make Grant his first name.
