'Iron Man 3' looking at Rebecca Hall as new leading lady
According to Variety, Hall "would play a scientist who plays a pivotal role in the creation of a nanotechnology, known as Extremis, that winds up being sold to terrorists." The film is scheduled to begin filming later in May.
Ben Kingsley has already signed on to play the villain, alongside Guy Pearce and returning stars Downey, Gwyneth Paltrow and Don Cheadle.
Chastain announced her decision to pass on the role on her Facebook page May 6, writing, "Sorry to say that 'Iron Man 3' isn't going to work out. My schedule is jammed packed and I can't fit anything else in. The press announced my possible attachment far too soon. I know many of you wanted me to be involved, and I'm so sorry to disappoint you. Hopefully there'll be another Marvel film in my future. Shane Black and everyone on the 'IM3' team are really wonderful. I'm very excited to see the film when it comes out," she says.
