Who played Crouch Jr in Harry Potter?

Answer 1

He works in the Ministry of Magic as the Head of the Department of International Magical Cooperation, and is one of the judges of the Twiwizard Tournament at Hogwarts until he mysteriously disappears. He used to be an appreciated and respected judge, (Head of the Department of Magical Law Enforcement) at the Ministry of Magic, during the First Wizarding War. He was pushed aside shortly afterward, as his son was revealed to be a Death Eater who'd possibly taken part in torturing two people into madness, and Mr. Crouch sentenced the boy to Azkaban for life. As in, people didn't understand how a son of someone like Barty Crouch could've done something like that, and some didn't like that the father sent his own son to Azkaban and naturally people came to have different opinions on him - mostly negative. However, the reasons how the father could do such a thing or if the son even really took part in the torture crime, are not confirmed in the book, and the possibilities are many.

Barty Crouch did send his son to Azkaban, where the son spent a year and was dying there before his dying mother took his place there. So, the father had agreed to save his son from Azkaban by letting the mother take his place and the son believed it was only out of love for the mother, granting her last wish. Mr. and Mrs. Crouch visit their son's death bed in Azkaban and make the switch with Polyjuice Potion. Mr. Crouch takes his son home and in order to protect the boy and keep him from searching for Voldemort, Mr. Crouch hides him from the world with the Imperius Curse and an invisibility cloak.

For twelve years he succeeds in that.

Answer 2
