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 the scene after Hiccup finally gets Toothless' new tail fin to work, and the two are relaxing after they fly through the fire ball, the two are greeted by a group of tiny dragons. This little dragon was actually what Toothless was originally going to be, as he was in the book, until they changed him to a dragon big enough for Hiccup to ride to suit the movie. (00:46:15)
Trivia: The "Bride in Black" is played by a man wearing women's clothing. This was done so that something would feel "off" about the image of the ghost. At the time, the character was intended to be female. However, when the creators later reused the character for the sequel and added in a backstory, they worked the fact that the character was played by a male as part of his backstory - it actually is a man who masqueraded as a woman as a disguise to lure in victims.
Trivia: Domhnall Gleeson, who plays Bill Weasley, is the son of actor Brendon Gleeson (Mad-Eye Moody).
Trivia: The CGI wolves have no genitalia in the Eclipse movie because they needed to maintain the PG-13 rating.
Trivia: In a shot of Zeus sitting on the throne, Emma Thompson, in costume as Nanny McPhee, is actually hiding behind the throne - they were filming next to each other. The story was related during an interview - she sneaked on set during a break, sat on Liam Neeson's lap and said "I think you've been a very naughty boy". He suggested she stay when filming resumed, as the shot wasn't going to be on him anyway, but she didn't want to throw off Ralph Fiennes, so hid behind the throne to get out of the way, and a shot of it with her hidden behind, unseen, is in the movie.
Trivia: When Nancy is drowning in the blood, the blood breaks through the floor to pour into the bedroom downstairs. This is a tribute to the original's famous bed-death scene where Johnny Depp is slaughtered by Freddy, causing the room to be drenched in his blood. (01:23:30)
Trivia: Alice's impending battle on the "frabjous day" with a creature referred to as a "Jabberwocky" is a central plot point, and refers to Lewis Carroll's famous poem "Jabberwocky," from which other characters in the film, such as the Jubjub bird and Bandersnatch, are derived. However, the titular creature of the poem "Jabberwocky" was NOT a Jabberwocky, but a Jabberwock. For whatever reason, the writers of the film chose to call it by the [admittedly similar] title of the poem instead of the actual name of the creature. (For the full text of the poem, see http://www.jabberwocky.com/carroll/jabber/jabberwocky.html).
Trivia: When Hobart falls off the fence when Ramona is mowing the lawn, he yells a Wilhelm scream.
Trivia: Madame Varcolac's name is Romanian for werewolf.
Trivia: When the goalie is scared away by Billy Crystal during the end credits, he yells the Wilhelm scream.
Trivia: The scene when Ramona delivers the package to Scott and he signs for it, he takes the package and throws it over his shoulder into the trash can, some several feet behind him. In the outtakes reel, they show that no special effects were used. Michael Cera made the shot over his shoulder on his 33rd attempt.
Trivia: Given that Clint Eastwood has composed much of the music for his films over the last 25 years, it's not surprising that the soundtracks of "Hereafter" and "Unforgiven" are incredibly similar, if not interchangeable.
Trivia: In the film, Amanda Peet plays Darcy Silverman. Peet also starred in the movie "Saving Silverman" as Judith who was engaged to the character Darren Silverman. Jack Black (Gulliver) also starred in "Saving Silverman"
