Continuity mistake: Obi-Wan's braided hair keeps changing sides, and getting longer and shorter, most noticeably in the scenes around the underwater city. (00:13:40)

Factual error: The radar guided SAMs are consistently evaded/triggered by the pilots' flares, which in reality only work against heat seeking missiles. Radar guided missiles would be defended against using chaff, basically clouds of aluminium foil strips. It was mentioned in some interviews they didn't want use chaff as it wouldn't really be visible for the audience - hence why they only deploy flares.

Continuity mistake: During Marty's drive to the bogus address, when he is done speaking with Monty, just as he says, "Wolf out!" he pulls the phone wire and the earpiece actually pops out of his ear, but in all of the following shots that earpiece is still in his ear. Since the super-glued earpiece is one of the main plot points, this is bizarre to say the least. (00:44:25)

Trivia: This is Michael Caine's final film. He decided to retire after making it, when he came to the realisation that, at age 90, he would only be landing roles of old men.

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.

Plot hole: At the start of the movie, a great deal is made of the boom mic that enters the shot. This is ridiculous, because Bolt's view would not be restricted to what was onscreen, he'd have a perfect view of the person holding the boom mic (as evidenced by it not being stable). There's no possibility of him not seeing the person holding the mic either. As Bolt completely and utterly believes the world he lives in, and thinks the situations he finds himself in (saving Penny) are real, someone holding a boom mic would break the illusion for him. In all instances in the movie where an outside force (i.e. a dog handler) interacts with him, Bolt never gets to see the person handling him (handler approaches from behind), the boom mic operator however is literally right in front of him.

Continuity mistake: Darth Maul's neck is black, but when he is talking to Darth Sidious on Coruscant, his neck is flesh-toned. (00:38:45)

Revealing mistake: When Cap is driving the blue Chevrolet Silverado with Black Widow, the gear shift is in the up locked position, not lower on the column, indicating the truck was towed in the scene. (00:54:45)

Other mistake: When Elastigirl is chasing the high-speed train, as she is in the middle of making her second final jump to reach the train, if one were to look closely, the train actually drives right past her before she lands. (00:31:40)

Question: When the lawyer told Nisi that Mr. B. "already knew" she wasn't Lily's granddaughter, did he know from the first day they showed up or from the day the lawyer came over to tell Mr. B. about what his nephew said about Mickey and Nisi?

Trivia: During the scene in the bar with Mystique and the prison guard, the person on the TV is Dr. Hank McCoy - this is the real name of X-Man The Beast.
