3. Iron Man (2008)
Iron Man is the film that kicked off the Marvel Cinematic Universe and it did so in a big way. Despite revisiting the stale origin story of a superhero director Jon Favreau was able to breathe new life into the plotline. A lot of that is thanks in large part to Robert Downey Jr.’s great performance as Tony Stark. Combining a great sense of humor with a lot of charisma, RDJ instantly became this character and proved to be a star once again. The only downside here is Jeff Bridges as a weak villain and a final fight scene that’s just as weak. Despite that this was the best film in this universe before these next two films were released.
