During the events of Harry Potter and the Goblet of Fire (2005) played by Roger Lloyd Pack
After the attack on the campground where the Quidditch Championship is being held, Harry Potter wakes up and is found by Ron Weasley and Hermione Granger and then by Barty Crouch and a group of Ministry Witches and Ministry Wizards. Barty initially accuses Harry, Hermione and Ron of conjuring the Dark Mark in the sky. Harry tells Barty that he saw a man nearby and Barty and the Wiches and Wizards head in that direction. At Hogwarts, Albus Dumbledore tells the students that Hogwarts will be hosting the Triwizard Tournament. Dumbledore introduces Madame Olympe Maxime and the students of the Beauxbatons Academy of Magic, including Fleur Delacour. He then introduces Igor Karkaroff and the students of Durmstrang, which includes Viktor Krum. The Goblet of Fire is brought into the hall and Dumbledore tells the students that whoever wins the tournament will have eternal glory. Alastor "Mad-Eye" Moody walks into the hall and is greeted by Dumbledore. Barty Crouch tells the students that no student under the age of 17 will be able to apply to participate for the Triwizard Tournament. During the champion selection, Cedric Diggory, Viktor, Fleur and Harry's names are chosen. Maxime and Karkaroff accuse Harry of cheating, but Barty Crouch says Harry must compete. As Barty Crouch is congratulating Harry for coming second in the second challenge, Moody walks up and Barty notices a mouth tick that Moody exhibits and seems to recognize it. Later, Harry finds Barty dead in the woods.
