Iron Man 2 is a 2010 American superhero film based on the Marvel Comics character Iron Man. Produced by Marvel Studios and distributed by Paramount Pictures, it is the sequel to Iron Man (2008) and the third film in the Marvel Cinematic Universe (MCU). Directed by Jon Favreau and written by Justin Theroux, the film stars Robert Downey Jr. as Tony Stark / Iron Man alongside Gwyneth Paltrow, Don Cheadle, Scarlett Johansson, Sam Rockwell, Mickey Rourke, and Samuel L. Jackson. Six months after Iron Man, Tony Stark resists calls from the United States government to hand over the Iron Man technology, which is causing his declining health. Meanwhile, Russian scientist Ivan Vanko uses his own version of the technology to pursue a vendetta against the Stark family.
Following the critical and commercial success of Iron Man in May 2008, Marvel Studios announced and immediately set to work on producing a sequel. In July, Theroux was hired to write the script and Favreau was signed to return as director. Downey, Paltrow, and Jackson were set to reprise their roles from Iron Man, while Cheadle was brought in to replace Terrence Howard in the role of James Rhodes. In the early months of 2009, Rourke (Vanko), Rockwell, and Johansson filled out the supporting cast. Filming took place from April to July 2009, mostly in California like the first film except for a key sequence in Monaco. Unlike its predecessor, which mixed digital and practical effects, the sequel primarily relied on computer-generated imagery to create the Iron Man suits.
With the world now aware that he is Iron Man, billionaire inventor Tony Stark (Robert Downey Jr.) faces pressure from all sides to share his technology with the military. He is reluctant to divulge the secrets of his armored suit, fearing the information will fall into the wrong hands. With Pepper Potts (Gwyneth Paltrow) and "Rhodey" Rhodes (Don Cheadle) by his side, Tony must forge new alliances and confront a powerful new enemy.
