The third "Iron Man" movie will reportedly borrow elements from the "Iron Man: Extremis" series, about how the hero deals with a virus that spreads through nanotechnology.
Jessica announced her departure from the Marvel project on Facebook, 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."
