Deliberate mistake: Bowser has several teeth that appear and disappear throughout the movie. The best example of this is when Mario is trying to grab the Power Star. We see Bowser snarl at Mario before he picks him up. There is a gap between his two front teeth. However, when the scene cuts from Mario's horrified face to Bowser's face, there are now extra teeth inside that gap.

Factual error: Why is Hilts not wearing a uniform? A serving officer captured behind enemy lines in civilian clothing risked being shot as a spy. If a prisoner's uniform was too worn or damaged to wear, it was routine for the German authorities to replace it - a P.O.W. in civilian clothes is an obvious escape risk. He is wearing a pair of tan chinos, a cut off sloppy Joe sweatshirt, both ridiculously anachronistic - Sixties hipster fashions - and nowhere even close to a World War 2 uniform. He is also wearing Army Type III Service boots - something that would never have been issued to a fighter pilot.

Revealing mistake: During Quidditch tryouts, when Ron blocks the Quaffle with his head in the closeup, Ron's body disappears at the bottom of the screen below the digital editing line. (Only visible on fullscreen DVD).

Trivia: Harriet's chair in the spirit session is styled after the vehicles in the Haunted Mansion theme park ride.

Continuity mistake: When they jump in the pool, they drop the guitar. When they jump out their guitar is no longer in the pool.

Trivia: In the last scene, when everyone meets to play poker, Catherine Zeta Jones throws her hands up to celebrate a win and falls out of her chair for real.

Factual error: Twice in the film it is made clear that the Pym particle works by reducing the space between atoms in order to shrink an object, and by increasing it to enlarge them. This means that the object will weigh the same, whether shrunk or enlarged - it cannot be otherwise. A 90kg man the size of an ant would punch a hole through any surface upon which he stood (and couldn't ride ants), Doctor Pym has been walking about with a 60 tonne tank in his pocket, Darren Cross lifts a full grown sheep between finger and thumb, and the supersized Thomas The Tank Engine would be far too light to crush the police car (in fact it would float harmlessly away as it would probably weigh less than the air it displaced).

Frank Castle: I leave this as a declaration of intent. So no one will be confused. One. Si vis pacum para bellum. Latin. The boot camp Sergeant made us recite it like a prayer. Si vis pacum para bellum. If you want peace, prepare for war. Number two. Frank Castle is dead. He died with his family. Number three. In certain extreme situations, the law is inadequate. In order to shame its inadequacy, it is necessary to act outside the law. To pursue natural justice. This isn't vengeance. Revenge is not a valid motive, it's an emotional response. No. Not vengeance. Punishment.

Continuity mistake: When Mrs. Otterton is in Chief Bogo's office holding her family photo with both paws, in the wideshots her purse is hanging in the crook of her left arm, but after a brief shot of Judy, when it cuts to Mrs. Otterton's closeup as she tells Bogo about her two beautiful children her purse is gone, then after another brief shot of Judy the purse is back in its place again in the wideshot.

Factual error: When they are trying to navigate the shuttle through Eadu, the shuttle abruptly collides with a rock, which causes Bodhi to jolt backwards. If the shuttle hitting the rock had caused the shuttle reduce speed so abruptly, in the way that was shown, then Bodhi would have jolted forwards, not backwards. (00:57:05)

Casual Person

Question: I never understood the significance of the girl in the wheelchair at the reunion. Peggy Sue makes a big deal out of the girl but never in her "flashback" do we see this character.
