With Emily Blunt having committed to the upcoming Gulliver's Travels, her previously-announced role in Iron Man 2 is now up in the air.
So, who might replace Blunt in the sequel?
Marvel is reportedly in discussions with Scarlett Johansson, according to Entertainment Weekly. The studio won't confirm such a rumor, but sources around Hollywood say the actress has met with filmmakers and is interested in taking the role of Russian spy Natasha Romanoff, who doubles as Black Widow.
Iron Man 2 still lacks shooting script and a production date has not yet been determined.
