The young British actor playing Ravenclaw student Marcus Belby in the upcoming Warner Bros. production Harry Potter and the Half-Blood Prince was stabbed to death during a fight in London on Saturday, according to Daily Variety. Rob Knox, 18, was one of five men taken to various hospitals after a brawl outside a bar. A 21-year-old is being held on suspicion of murder.
Knox plays a fairly minor role in Harry Potter and the Half-Blood Prince, the sixth movie based on the popular series of books by author J.K. Rowling. The vfx-driven film is slated to hit theaters this November.
