Trivia: When Gordon is promoted to Commissioner, Heath Ledger improvised the Joker joining in with the applause.

Trivia: A little foreshadowing - when the King first goes to the Poison Apple pub, a frog with ruby red lips asks him if she has met him before.

Trivia: Jeremy Sumpter (Peter Pan) had to go through 6-7 months of flying practice before he could start "flying" in the film.

Trivia: Music composer John Williams has a cameo as a bartender on the planet Kijimi.

Trivia: Director Jason Reitman is the son of Ivan Reitman, director of the original "Ghostbusters" and "Ghostbusters II." As a child, Jason actually had a cameo in "Ghostbusters II" during the birthday party in the beginning. (He's the kid who tells Ray he heard the Ghostbusters were "full of crap").

Trivia: Tippi Hedren actually received a cut on her face by a bird in one of the shots.

Trivia: When the Grinch takes the table cloth from the table, everything on the table was supposed to fall off. When Jim Carrey yanked out the cloth however, everything stayed in place. Jim immediately walked back to the table and improvised knocking everything off and then knocking the table over.
Suggested correction: There is no evidence this was a mistake.
There's an apparent scan of an original script on scriptslug.com that indicates the scene, as written, had him pulling the cloth without disturbing anything, then kicking the table over.

Trivia: The English translations for the majority of the German dialogue towards the end of the film, as taken from recent BBC TV airings:
(Outside the house just before Mr Brown enters back in)
Guard: Yes, Yes everything is fine.
(as Mr Brown tries to stop Cosmic Creepers yowling)
Guard: What's that?
(after the guards enter Miss Price's house after hearing the yowling)
Guard: It's just a naughty cat, poor thing.
(after capture of Miss Price, the guard sees Mr Brown as a rabbit)
Guard 1: Jagged hare, this will be good.
Guard 2: Idiot, Do you want to wake up the whole village!
(on the battlefield, prior to Miss Price casting her spell)
Guard 1: Colonel, The bridge is ready to blow.
Guard 2: The railway, road and quay are ready.
Colonel: Good. We detonate in ten minutes. Get everything primed for then.
(start of the march)
Colonel: It's got to be some kind of trick.
Guard: Pretty good trick!
(first sighting of Miss Price by the Germans)
Guard: It's a witch sir!
Colonel: Don't be a fool, there's no such thing as a witch!
(after seeing the size of the army of advancing inanimate objects)
Guard: Shall we retreat sir?
Colonel: Retreat? We are German Soldiers! We do not retreat!
(as the Germans are running away)
Colonel: Hold the line or I will shoot you! You are German soldiers!
(back at the house after having been forced to retreat)
Colonel: There is the witch.
Guard: You said there was no such thing as a witch.
(prior to blowing Miss Price's house up)
Colonel: What are you waiting for, leave nothing behind. Quick, detonate it.

Trivia: In the scene of Missy's funeral, Stephen King plays the priest.

Trivia: Johnny Depp uses the phrase "Interesting..." as his trademark in many of the movies he stars in, including Sleepy Hollow. He uses it in PotC when Koehler's skeletal hand tries to grab him in prison.

Trivia: Johnny Depp passes an old bald man with hippy glasses sitting down surrounded by women - this is author Hunter S. Thompson himself in a cameo.

Trivia: All of the creatures in baby Rapunzel's mobile are referenced later in the movie. The blue bird is the first creature she encounters after leaving the tower (it flies around her head when she sings "completely free"). There is also a white horse (Maximus), a chameleon (Pascal), a yellow duck (The Snuggly Duckling), and a cherub (the old man who dresses like an angel in "I've got a Dream").

Trivia: In order to acquaint himself with his three lead actors, director Alfonso Cuaron had each of them write an essay about their characters, from a first-person point of view. Emma Watson, in true Hermione fashion, went a little overboard and wrote an 16-page essay, Daniel Radcliffe wrote a simple one page paper, and Rupert Grint never even turned his in, as he said that is what Ron would have done.
