Jessica Chastain has denied that she will appear in Iron Man 3.
The Oscar-nominated actress had been eyeing the role of a "sexy scientist" - who rivals the intelligence of Robert Downey Jr's character (Tony Stark) - in Shane Black's third instalment of Marvel's superhero series.
However, Jessica has now revealed that she has been unable to take the part due to scheduling conflicts.
"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," she wrote on her Facebook page.
"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."
The actress added: "I'm very excited to see the film when it comes out."
