Iron Man 2 Official Trailer

Can't wait for the release of this movie sometime around May this year. Hopefully it will be as good or better than the first.

Cast
Robert Downey Jr. as Tony Stark/Iron Man: The head of Stark Industries, inventor and the film's eponymous superhero and protagonist.
Don Cheadle as Lt. Colonel James "Rhodey" Rhodes/War Machine: Cheadle is replacing Terrence Howard from the first film. Howard said, "There was no explanation, apparently the contracts that we write and sign aren't worth the paper that they're printed on sometimes. Promises aren't kept, and good faith negotiations aren't always held up." Entertainment Weekly stated Favreau did not enjoy working with Howard, often reshooting and cutting his scenes; Howard's publicist said he had a good experience playing the part, while Marvel chose not to comment. As Favreau and Theroux chose to minimize the role, Marvel came to Howard to discuss lowering his salary – Howard was the first actor hired in Iron Man and earned the largest salary of the cast. The publication stated they were unsure whether Howard's representatives left the project first or if Marvel chose to stop negotiating.Theroux denied the part of the report stating "the role of War Machine was scaled back and then beefed up".Cheadle only had a few hours to accept the role and did not even know what storyline Rhodes would undergo. He commented he is a comic book fan, but felt there are not enough black superheroes. The character will don the War Machine armor in the film.
Mickey Rourke as Ivan Vanko/Whiplash: This version of the character includes elements of both Whiplash and Crimson Dynamo from the comics. In the film, he will be the son of Russian scientist Anton Vanko, who, in the comics, is the original Crimson Dynamo and creator of said armor. Downey offered Rourke the part during a roundtable discussion with David Ansen at the 2009 Golden Globes, and Rourke met with Favreau and Theroux to discuss his character's role. Rourke almost dropped out of the role due to Marvel's initial salary offer of $250,000, so the studio chose to increase the deal. Rourke researched for the part by visiting Butyrka prison. He suggested half of the character's dialogue be in Russian. Whiplash will act as the main antagonist of the film. In the trailer, he is shown using electric whips.
Gwyneth Paltrow as Virginia "Pepper" Potts: Stark's closest friend, budding love interest, and business partner after Pepper replaced Obadiah Stane as CEO of Stark Industries.
Scarlett Johansson as Natasha Romanoff / Black Widow: An undercover spy for S.H.I.E.L.D. posing as Stark's assistant.. Johansson was cast after a scheduling conflict forced Emily Blunt to drop out of the part.
Sam Rockwell as Justin Hammer: Rockwell was considered for the role of Tony Stark in the first film, and he accepted the role of Hammer without reading the script.He had never heard of the character before he was contacted about the part, and was unaware Hammer is an old man in the comics, whereas in the film he will be significantly closer to Stark's age. Originally thought to be a major antagonist, Rockwell says his character is "plucky comic relief, but he’s got a little bit of an edge".
Samuel L. Jackson as Nick Fury: Jackson initially had financial problems with Marvel and was unsure about reprising the part of Fury, until they reached a deal that would entail his appearance in up to nine films as the character.
Jon Favreau will reprise his role as Happy Hogan, Tony Stark's bodyguard and chauffeur. John Slattery will appear as Howard Stark, Tony's father.
