Chatting with Jimmy Kimmel, actor and director Jon Favreau, known for helming the Iron Man movies and appearing in them as Happy Hogan, has said that he would play Dungeons & Dragons while growing up. "It was really good preparation for being a filmmaker," he remarked. "It did help me when you build worlds for making a superhero movie or dealing with CGI and filmmaking. Between that and doing improvisational comedy in Chicago, those two things, I really draw from."
