The Marvel Cinematic Universe has become a 33-film-wide mega-franchise, and it all started with 2008’s Iron Man (which is streamable for Disney+ subscribers). Sure, Marvel Entertainment had more than dipped its toe into superhero blockbusters prior to Robert Downey Jr. taking on the role of Tony Stark, with flicks like Blade, X-Men and Spider-Man. However, Jon Favreau’s movie -- the first production under the comic brand's independent studio -- indisputably changed cinema. With his superhero days behind him, RDJ recently opened up about working on the iconic film before the cinematic universe got big.
