Trivia: This is for the trailer rather than for the final film, but worth a look. At 1:33 in the trailer, just after seeing Rorschach slam someone against a wall, we see another fight. Pause it and look at the guy in black - he's holding a walkie-talkie, which in the next shot becomes a gun. This is only trivia, not a mistake, because it's only valid for the trailer. The MPAA don't allow guns to be pointed at the screen in trailers, so Zack Snyder, in a tribute to the infamous gun-editing from E.T., replaced the gun in that one shot with a walkie-talkie.

Trivia: A popular film poster shows Emily and Victor reaching their hands toward one another. Emily's bony hand is on her right and Victor's suit and vest are backwards (note its buttons). Some say it was for legal reasons - Johnny Depp's name was supposed to appear on the poster first because of a contract, and they wanted the characters underneath the corresponding star names, hence the issue. Others say it was simply because the picture looked better with the bride on the right side.
Trivia: When Skinner stops chasing Remy, a mime artist is visible in the background. This man is none other than Bomb Voyage, a character from The Incredibles, Pixar's previous production. (01:17:30)

Trivia: When Olaf just starts to sing "When I Am Older" count for about 10 seconds and watch the fire jump from tree to tree. If you watch the right side of the screen closely at the 10 seconds point, you can see the fire briefly take the form of Mickey's head.
