Rebecca Hall in talks to join cast of "Iron Man 3"

Variety reports that Rebecca Hall (The Prestige) is in talks with Marvel to join the cast of "Iron Man 3" as the female lead. She'll reportedly play a nanotechnology scientist. Her invention, called "Extremis" winds up in unsavory hands and leads to all sorts of trouble for Tony Stark.

Filming begins later this month with the 3rd installment in the Iron Man series due out May 3rd next year.
