Marvel Studios is in talks with Rebecca Hall to play the female lead in their superhero sequel Iron Man 3. We reported that Jessica Chastain had passed on the role due to scheduling conflicts yesterday.

Plot details are minimal, but it is rumored that Iron Man will head to China to face his toughest opponent, Mandarin. The actress will play a scientist who plays a pivotal role in the creation of a nanotechnology, known as Extremis, that winds up being sold to terrorists.

Production on the film starts this month in North Carolina before heading to China.
