The Triwizard Tournament was at the center of the Harry Potter and the Goblet of Fire plot, but a good deal about the competition was left out of the movie adaptation. This was true for several of the Harry Potter films. However, due to the complex nature of the story surrounding Harry's fourth year at Hogwarts, the Goblet of Fire movie is especially known for cutting even important book details.
Crouch and Bagman did not see eye to eye. For a time, this made Bagman seem like one of the top suspects for having put Harry's name in the Goblet since he seemed to take an unethical interest in the Boy Who Lived's victory. Of course, it wound up being that he had put a sizeable bet on Harry getting the Triwizard Cup, and if the boy failed, he would be in hot water with the goblins of Gringotts. When everything shook out in the Goblet of Fire book, Bagman went on the run.
3 Dobby Played An Important Role In Harry's Second Triwizard Task Victory In the Goblet of Fire movie, Harry owed his success in the second Triwizard Task to Neville Longbottom, who pointed him in the direction of Gillyweed. It was a simple enough solution that made sense given Neville's passion for herbology, but it was still a disappointment to book fans.
