Domhnall Gleeson (Bill Weasley)
Gleeson performed in school plays, and later went on to study arts and direct and write for film and stage right after graduation. At first reluctant to act alongside his father, Domhnall joined the cast of Harry Potter (where his dad played Alastor Moody) to play Bill Weasley in 2010. Before the magical movies came out, Domhnall already had a few roles in various films like HBO television film A Dog Year and Sensation. However, his career breakthrough followed after the Potter series were wrapped up. Gleeson went on to play in films such as Never Let Me Go, Anna Karenina, Ex Machina, Star Wars: The Force Awakens, and more.
