The Iron Man 2 casting rumors have become a reality.
A rep for Scarlett Johansson has confirmed that actress will play Black Widow in the sequel, which is scheduled for a May 2010 release.
"Scarlett is thrilled to be a part of Iron Man," the rep told E! Online.
Meanwhile, after a series of negotiations, Mickey Rourke has also agreed to his much-rumored role: he'll portray the villain Whiplash.
