After the movie about Iron Tony, its sequel and another four superheroes films were released over the next four years: about Thor, Hulk and Captain America. They were not as successful as the solo Iron Man films, but their union in "The Avengers" in 2012 was quite natural. The superheroes joined together in the fight against alien invaders and the cunning god Loki, and this movie quickly became the most important and lucrative for Marvel Studios. The film's director Joss Whedon filmed a harmonious mix of science fiction, big-budget action and comedy.Photo Universal She-Hulk by JD Hancock is licensed under CC BY 2.0.
