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: The CGI wolves have no genitalia in the Eclipse movie because they needed to maintain the PG-13 rating.
Trivia: Glee's Dianna Agron makes a cameo appearance as Jack's fiancee, Natalie.
Trivia: The Marni family's home in this movie is the same house Jamie Lee Curtis resided in in the 2003 movie Freaky Friday.
Trivia: Robert Pattinson was actually injured during breaks while doing a street scene - hordes of fans chased him out to the street and he was hit by a passing car. Though he was not fatally injured, he was somewhat shaken during the ordeal. Bodyguards and assistants came to his aid and shielded him from the overzealous admirers.
Trivia: Christopher Plummer won the Best Supporting Actor Academy Award for his role as Hal Fields. At the age of 82, Plummer became the oldest winner in Oscar history.
Trivia: At the beginning of the movie, Olive wonders why her life can't be more like an '80s movie, including Sixteen Candles. In the car with Todd, when they're - SPOILER ALERT! - talking about kissing each other, the song playing in the car is a rendition of "If You Were Here," the song playing near a similarly romantic scene in Sixteen Candles.
