Gunn's not alone in his opinion: Paddington 2 is a big hit with critics. At one point, it was the only movie on Rotten Tomatoes with a perfect 100% score (ousting Orson Welles' 1941 classic Citizen Kane from the site's highest-rated top spot), but now it sits at a still pretty impressive score of 99%.

Director Richard Donner’s Superman: The Movie, which premiered in 1978, is a classic piece of cinema that continues to shape the superhero genre today. Most recently, it led the way for writer-director James Gunn to release Superman, a more modern imagining of the Man of Steel’s adventures, with David Corenswet portraying the titular hero.
