And another late arrival in today’s trailer bin, which will also presumably be featured before Avatar tomorrow night: The Stark family past catches up to Tony (Robert Downey Jr.) in the teaser for Jon Favreau’s eagerly-anticipated Iron Man 2, also with Gwyneth Paltrow, Don Cheadle (replacing Terrence Howard as Rhodey), Scarlett Johansson, Sam Rockwell (blink and you’ll miss him), Samuel L. Jackson, Garry Shandling, and Mickey Rourke. Yes, they made a sequel to the movie about the trailer…From a fanboy perspective, I’m still thinking Johannson is badly miscast as the Black Widow. Otherwise, this looks like more of the same — Count me in.
