Scarlett Johansson in Negotiations to replace Emily Blunt in Iron Man 2

[Brian Damage]

Scarlett Johansson is in talks to replace Emily Blunt as 'The Black Widow' in Marvel's "Iron Man 2", according to EW.

EW reported the following :

Because Emily Blunt's commitment to Twentieth Century Fox and the studio's upcoming Gulliver's Travels movie may prohibit her from costarring in Iron Man 2, Marvel is in discussions with other actresses, most significantly Scarlett Johansson, to take her place, EW has learned exclusively. Marvel will not confirm, but sources around Hollywood say Johansson has indeed met with the filmmakers and is interested in taking the role of Russian superspy Natasha Romanoff, who doubles as Black Widow. Blunt's reps are still trying to make both projects work, but Gulliver's is further along, with a start date of April 15. Iron Man 2 still doesn't have a shooting script and a start date has not yet been determined.
