Iron Man 3 (rated PG-13)
The returning cast includes Robert Downey Jr. as Tony Stark, Gwyneth Paltrow as Pepper Potts, Don Cheadle as Rhodey, Jon Favreau as Happy, and Paul Bettany as the voice of Jarvis.
After the events of "The Avengers", Tony Stark is still struggling with the aftermath of that alien invasion. He's become withdrawn and obsessed with getting ready for the next big threat, so he's been doing nothing but building new suits.
This movie starts with him having FORTY-TWO variations. And the latest version, the Mark XLII, allows him to summon the suit to himself by using sub-dermal implants.
That new model also lets him direct his armor to another person, which is how Pepper gets it when he protects her from the Mandarin's choppers. You'll see a lot of his suits destroyed in that attack, and Downey spends a lot of the film without the Iron Man suit.
Ben Kingsley plays the Mandarin, who comic fans know to be one of Iron Man's greatest enemies. In "Iron Man 3" he initially comes across as a modern-day terrorist.
He's the movie's main villain, but Tony also has to fight some super-powered humans who've been genetically enhanced by some bio-technology called Extremis that, among other things, gives them to power to heal themselves.
And finally, this will be the first of the Marvel movies where Samuel L. Jackson doesn't make a cameo as Nick Fury. Instead, the post-credit scene that we've all come to expect will feature Mark Ruffalo as the Hulk's alter-ego, Dr. Bruce Banner.
