Continuity mistake: In the scene where Edward and Carter are on the plane, Edwards book keeps changing position from mostly open to mostly closed, as well as the amount read varies.
Continuity mistake: When Edward is first wheeled into his room and Thomas, the doctor and the nurse are standing over him, the nurse changes from standing next to Edward's head to standing right in front of the doctor and back again between shots, without time for her to move.
Factual error: When Cole and Carter are skydiving, there are a number of inaccuracies. First, Carter and his instructor jump well before Cole to put a safe distance between them. However, Cole and his instructor immediately catch up to Carter and then match their speed. This could be achieved by skilled jumpers, but not by instructor-novice pairs. Second, the men have a conversation while free-falling, which is completely impossible. Third, Carter pulls his own rip-cord (too early) and Cole's instructor yells at him to pull his own cord before it's too late. In reality, the instructor always carries the chute and pulls the cord for a first-time jumper, for exactly these reasons.
Continuity mistake: When Nicholson and Freeman's characters are arguing in front of the daughter's house, you can notice that Nicholson's shirt collar flips back and forth from inside his jacket to outside as the camera angles change.
Continuity mistake: After Carter's wife has just left the first time she visits, Edward's head goes from being on the pillow to off the pillow on the bed throughout the rest of the scene.
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.
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: 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.
Audio problem: When Edward and Carter are arguing at the daughter's house, Edwards says, "Presidents have asked my advice." Although the camera is on Carter, Edward's mouth movements don't appear to match what he said.
Continuity mistake: During the scene in which Carter and Cole are discussing faith while flying in the aeroplane, the clouds seen in the window behind each character do not appear to move at all, even though the speed of the plane should leave them behind very quickly.
