J.K. Rowling’s Harry Potter franchise has been entertaining audiences for decades, and is showing no signs of slowing down. The property continues to expand with theme parks, stage plays, and the Fantastic Beasts movies. Director Chris Columbus helped to kickstart the Harry Potter films, directing the first two installments and going on to serve as a producer for the third. And while he originally wanted to return to helm the two-part Deathly Hallows films, Columbus recently explained why he’s glad this didn’t work out.
