Update: Variety reports that Rebecca Hall has replaced Chastain in the role. According to Variety, Hall 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.”
Jessica Chastain has written a note on her Facebook page revealing that she will not be starring in Marvel’s upcoming Iron Man 3:
“Sorry to say that ‘Iron Man’ 3 isn’t going to work out,” she writes. “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. xx”
Iron Man 3 is scheduled to hit theaters on May 3, 2013. Shane Black is directing and co-wrote the script with Drew Pearce.
