During an interview with BuzzFeed, Daniel Radcliffe said that the death of Sirius Black (played by Gary Oldman) in the “Harry Potter” movie franchise was the hardest to get over. The actor explained that the moment was tragic because he “adored” working with Oldman and didn’t know if he would get the chance to do so again. Business Insider reports Radcliffe adding, “the character’s death just comes so out of the blue as well” and “was a real shocker.”
