Iron Man
2008 · Jon Favreau · 126 min · Action / Sci-Fi
Iron Man is the film that launched the MCU, and it succeeded because it was a great film first and a franchise starter second. Robert Downey Jr.'s Tony Stark is the most perfectly cast superhero in cinema history, bringing charisma, humor, and vulnerability to a character that the film builds from weapons dealer to hero through a transformation that feels earned. The third-act villain battle is the weakest element, falling into generic CGI spectacle after two acts of character-driven brilliance, but Downey's performance ensures the film transcends its genre.
