Revealing mistake: When Fletcher is beating himself up he goes into a stall and squishes his head with a toilet seat. You can see that the white part underneath is made out of foam because it keeps squashing down.
Factual error: A minor only has a certain amount of time (typically, 6 months) to invalidate a contract entered into when such person was underage once that person turns 18 (or the age of emancipation in that state). This brings up a plot hole: If the marriage was not invalidated because Samantha Cole was underage, the prenuptial agreement would not be either, and Fletcher could not have used that argument to win the case, since he specifically states that she was seventeen at the time of her marriage.
Continuity mistake: The gift changes position from when Gretta holds it to when Fletcher takes it away. (00:08:45)
Other mistake: Tower Air never had direct flight service to Boston, only to NY from LA.
Continuity mistake: When Fletcher is in his office and he's trying to write that the pen isn't blue, he swipes everything from his desk and there's then an overhead shot showing the only thing left on his desk is a small piece of white paper on the right hand side. A few seconds later the piece of paper has disappeared and has instead been replaced by the telephone line.
Other mistake: When Fletcher is attempting to force himself to write the word "red" on his desk, in the shot before the "blue" is revealed, his pen is not even touching the desk and his final pen movement is a curve which doesn't correspond to an exclamation point.
Suggested correction: He had already finished writing "blue!" by the time we see the shot of him holding the pen off the desk. He was probably making the motion of writing "red" (with the curve you see corresponding to the "d") not realizing that the pen wasn't touching the desk, and not realizing that he had already finished writing "blue." Hence his initial gleeful reaction-he thinks he's successfully beat the spell, until he sees the writing and realises he hasn't.
Continuity mistake: When Fletcher moves underneath the wing of the plane on his flight of stairs, another plane is seen in front of him. It disappears when the pilot sees the shoe land on the windscreen. There is also no sign of the barrier and luggage area that he crashes into a few seconds later. (01:14:50)
Continuity mistake: In the scene where Max is being driven to school,you can see that sometimes he has his seatbelt on, sometimes not.
Continuity mistake: When Fletcher takes his son to the office, they step out the lift and a woman in a purple suit is seen walking to the left. In the next shot, the same woman is walking to the right. (00:06:25)
Suggested correction: That's a different woman with a different hairstyle. The second lady's hair is up over her ears and the first woman's suit is a darker purple.
I don't think there's enough detail in the wide shot to say it's a different woman or not. She's seems to be carrying the same clipboard in the same way. Plus, in the next shot, the first woman should still be seen somewhere in the wide shot off to the left, and she's not.
Again. In the wide the woman's hair is up. You can even see a pin in it. It's not in the first shot. Also, she would not necessarily need to be seen in the wide shot. The first shot has them in the elevator, then there's a hallway, before they cross the doorway into the lobby. She would have already walked past the desk (notice the lamp) by the time they were a few inches out of the elevator. By the time they walked to the doorway she could easily be out of frame.
Impossible. The very short distance she walks takes her almost 2 seconds, and then she's off camera for maybe a second. The distance to the hall to be out of the shot is almost twice the distance she was just seen walking.
Depth perception. She's walking directly in front of the desk. She's not in the same spot as the second lady (in front of the lobby door). She walks across the screen before Max's feet leaves the elevator. The distance between the left side of the desk and off screen is fairly short and plenty of time for her to cross before they exit the elevator. Third time...different hairstyle. I'm pretty sure the second lady is even wearing a different shirt underneath her jacket too.
Audio problem: When Fletcher gives Max his birthday gift, the shot changes as Fletcher starts to say, "I hope it's not partially digested." When Fletcher's face comes into that shot, you can see that his lips aren't moving.
Continuity mistake: When Greta is packing her belongings away in a box, objects like rubber bands keep appearing in front of it, without her putting them there. The angle of the box changes as well. (00:44:15)
Revealing mistake: During the scene when Fletcher pummels himself in the courthouse restroom, the walls shake when he throws himself against them. The restroom walls were some type of marble or granite, and in real life would be very thick and rigid, making it very obvious this was a movie set.
Continuity mistake: Just before Greta hands Fletcher his son's birthday present, the cup and saucer on her desk disappears and re-appears between shots. Her glasses and the gift to herself also change position. (00:07:45)
Continuity mistake: In the scene where Fletcher is driving the flight of stairs, and trying to catch up with the Tower Air jet, the sky changes from cloudy, to clear, to partly cloudy throughout the scene.
Continuity mistake: In the scene where Fletcher is beating himself up in the bathroom, he gets a black eye. Throughout the rest of the movie, it disappears and reappears.
Continuity mistake: During Max's birthday party near the beginning of the film, Audrey takes the cake out of the box and places it on the kitchen counter, and then puts birthday candles on the cake. In the next shot, the cake is sitting on a glass plate that wasn't there before. (00:17:10)
Continuity mistake: Towards the end, Fletcher is on the stretcher talking to Max, and looks at his watch to discover he has been able to lie for half an hour. Max then responds "So you lied?". Fletcher then grabs Max's shoulder with his left hand, saying "No! It was the truth!". As the angle changes he is still speaking, but his left hand is now lying across his chest before he reaches out to grab Max again.
Continuity mistake: Just after Fletcher steals the yellow airfreshener from the car yard, he has his arms by his side. When the shot switches back to him, he has his arm on the counter. Considering that he was watching his car in such a shocked state, it's incredibly unlikely he would change to this position. (00:34:40)
Revealing mistake: In the scene where Fletcher drives out of the parking garage almost causing a car accident, you can tell it's his stunt double, because his stunt double is wearing sunglasses and doesn't look too much like Jim Carrey. Then it shows a back view of Fletcher speeding away and his sunglasses are gone.
Suggested correction: There are no sunglasses on the stunt double.
Continuity mistake: When the Boeing 747-200B initially taxis out from the gate, the flaps are set for take-off. After the stairs get hijacked, the remaining shots show the plane with the flaps retracted.
