13. In which movie do Fred and George Weasley fight each other, rolling around on the floor as they sprout long beards?
From Quiz Epic Struggles in the "Harry Potter" Movies
Answer:
Harry Potter and the Goblet of Fire (2005)
Many students are keen on submitting their name into the Goblet of Fire, in the hopes of being chosen as the Triwizard Champion for Hogwarts. Because the three tasks are so dangerous, the tournament has been restricted to students 17 years of age and older. Fred and George concoct an aging potion, in the hopes of fooling the age line that Dumbledore has drawn around the Goblet. They think that it works at first, but then the Goblet spits their names back out. When their hair turns gray, and they start growing long gray beards, they begin to wrestle one another, each blaming the failure of their scheme on the other.
Everyone at Hogwarts is excited about the upcoming Triwizard tournament. Voldemort arranges to have the cup turned into a portkey, so that Harry is brought to him when he touches it. In the graveyard outside of Voldemort's father's home, Harry's blood is used in a ceremony to bring Voldemort back to his corporeal form. Unable to stop Voldemort's return, Harry does manage to escape, to give warning of the Dark Lord's return.
