More Iron Man 2 news: Scarlett Johannson joins cast!

Just a few minutes ago we informed you all of the news that The Wrestler star Mickey Rourke had been cast in Iron Man 2.  Now comes word that Scarlett Johannson is cast in the film as well after replacing Emily Blunt.    Now apparently Johannson wanted the part bad enough that she actually screen tested for the part, accepted a low offer, and contracted to appear in a series of films to include the upcoming Avengers film, which is tentatively scheduled for a 2011 release date.
