In one of the challenges for the Triwizard Tournament in "Goblet of Fire," Harry ends up working with a dragon, except the whole ordeal is pretty vicious. A beloved children's film, "How to Train Your Dragon "is somewhat similar to "Harry Potter and the Goblet of Fire," except cuter and without the terrifying Death Eaters. In this family favorite, a Viking teenager named Hiccup must capture and slay a dragon to become a man. Though Hiccup's father is the chief of his clan, Hiccup doesn't actually care for fighting dragons. While in dragon-fighting school, he instead befriends and cares for a dragon he names Toothless. Plus, there are two sequels to enjoy.
