Other mistake: When Twoie first appears he is naked because he was just made. Yet when he walks toward the mirror, you can see at the bottom a strip of blue jeans.
Other mistake: The scene where Clear is in the garage, she puts the car in drive, but somehow reverses the car through the garage door. (01:24:49)
Other mistake: When Nick thinks he is going to be promoted he talks to his PAs about moving to the 44th floor. In the shot of the office building (after he leaves the coffee shop on the way to work) it's obvious that the building only has about 10 floors.
Other mistake: When Martha May is getting ready to put up her lights with the cannon, she pulls a charging handle, and starts firing. If you watch closely, you see a lit string of lights come out, but the spool that they're on isn't moving, or lit up. Then after all of the lights are out, it still fires several more times (watch the aiming indicator- it continues to flash with the sound).
Other mistake: Bruce Willis's character has a very clear scar on his forehead in some scenes (I think it's on the right as you look at him) - doesn't really fit the whole "unbreakable" theory. You'd think they could have put some makeup on it...
Other mistake: Mr. Gellar never ages. We see a flashback of him when he kills Sarah's Dad when Sarah was a little girl. When Sarah is a detective, he still looks the same.
Other mistake: The wet nurse that cares for the newborn Titus is pregnant when she is hired. She is far enough along to be producing milk, yet doesn't give birth until Titus is a year old.
Other mistake: The second time Virginia goes down the slide in the 9th Kingdom, you can see that it is a stunt double hurrying to get off at the end.
Other mistake: When Ariel hugs the adult Flounder, his eyebrows suddenly turn blue, then change back.
Other mistake: When Elliot the genius homosexual and Allison arrive at his apartment he hangs her wrap on the arm of the statue. He then begins to take off his overcoat and hangs it on the other arm. There is a cut to another angle and the coat is already hung on the arm and he is sliding out of it. There was not enough time for this transition to happen. (01:02:15)
Other mistake: Jack's friend Bill (Tom McGowan) was scheduled to have heart bypass surgery, but he is bowling the next day or shortly thereafter.
Other mistake: When Tai is typing an e-mail of apology to Sora, he accidentally types "Love Tai" as opposed to "From Tai" which he finds more appropriate. At that moment, Kari walks in, resulting in Tai's embarrassed stumble into the keyboard. We then see a highlighted "From Tai" change into "Love Tai". It is possible that Tai had already changed it before we saw it and then accidentally pushed Ctrl+Z upon Kari's arrival, but this is more than doubtful.
Other mistake: When Nicky is expressing his trepidation about going up to the Earth realm, he states that he's never even slept over at a friend's house. Later when he is on Earth, Beefy has to remind him to try sleeping, as Nicky had no idea what it was.
Other mistake: When Rocky jumps off the lighthouse in a failed effort to fly, he falls and hits the ground. Once on the ground, we see his goggles are unevenly on because of the crash. However, one of his goggles actually goes through his head.
Suggested correction: According to a previous explanation, David's "unbreakableness" is limited to his bone structure and general health. His skin can break and heal naturally. See the correction on why the scar from his ear piercing shows.
Twotall
When David wakes up in the hospital, Dr. Dugan tells David that he doesn't have a scratch on him. If his unbreakableness was limited only to his bone structure, he should have woken up covered in scratches from not only the force of the collision but also from the glass as he was sitting next to the window.
