Continuity mistake: As Ed and Carter are enjoying dinner in the elegant restaurant in France, note the plate of cookies to the left of the screen when the camera is on Carter. As the camera cuts back and forth from Carter to Ed as they chat, the cookies seem to come and go. The plate first has three cookies, then there are a lot of cookies when the camera cuts back to Carter again, then next there are four cookies on the plate in the next scene, etc.
Continuity mistake: While racing around the race track, Carter is shown in the inside lane while Edward is in the outside lane (seeing as how Carter looks to his right and Edward looks to his left as they're talking to each other) just before they jump over the pile of dirt. However, just after Carter says "pick up on this, chicken man" he turns the car quickly to the left, mysteriously appears in the outside lane, and cuts Ed off before making the jump.
Continuity mistake: When Jack Nicholson is sitting in a chair in the hospital room and Morgan Freeman is in the hospital bed, a nurse shaves Jack Nicholson's head bald with electric clippers from front to back. When the nurse finishes, the camera changes to a wide shot that shows there is no hair on Jack Nicholson and no hair on the floor.
