1. Goblet of Fire was almost two movies. Harry Potter and the Prisoner of Azkoban director Alfonso Cuaron convinced Director Mike Newell to make it cut the subplots and make it only one.
2. During the filming of the second task in the lake, Daniel
Radcliffe and several of the cast and crew members posed for a picture
underwater that later became Daniel Radcliffe’s Christmas card – he
added Rudolph noses and antlers.
3. Actors portraying Hogwarts students were given almost three weeks
of dancing lessons while the Yule Ball scenes were being filmed. Since
Daniel Radcliffe appears in almost every scene, he only had four days
of practice. For this reason, all scenes of him dancing are from the
waist up so his lack of dancing prowess wouldn’t be as obvious.
4. Over 3,000 girls showed up to audition for the role of Cho Chang.
Katie Leung, who finally landed the role, hadn’t intended to audition
but had time before her shopping trip and went on a whim.
5. The names of Voldemort’s Grandparents/Tom Riddle Senior’s parents
aren’t actually stated in the book, but are pictured on the graves in
the graveyard. The names Thomas and Mary came directly from J.K.
7. The rock band at the Yule Ball is called “the Weird Sisters” in
the books. In the movie, the band – comprised of members of Radiohead
and Pulp – is not named. However, “the Wyrd Sisters” a Canadian band,
attempted to sue filmmakers, claiming that their name was stolen. In
reality, J.K. Rowling took the name of the band from William
Shakespeare’s Macbeth. The Wyrd Sisters attempted to stop film distribution in Canada but the case was dismissed.
8. Twins Padma and Parvati Patil, whom Harry and Ron take to the Yule
Ball, are played in the movies by unrelated actresses, Afshan Azad and
9. In Iceland, young movie-goers were known to laugh when the
character of Rita Skeeter was first introduced during movie screenings.
The name “Skeeter” sounds very close to the Icelandic word "skíta," a
vulgar slang term that means to defecate.
10. The hedges in the third task were a homage to Stephen King’s The Shining. Reportedly, Stephen King happens to be a huge Harry Potter fan.
