Sunday night during the Oscars, Jon Favreau released the new Iron Man 2 trailer. There had been a previous trailer out for some time, but this one really gets you jazzed to see the new flick. Robert Downey Jr. is back as Iron Man, with Don Cheadle at his side. Mickey Rourke takes on the roll of the villan, and hollllllly shit, hes going to kill it. Gwyneth Paltrow, Scarlett Johansson and Sam Rockwell will all be supporting characters, and if the trailer is any indication, this is a must see.
