Deadline is reporting that Jessica Chastain (The Help) is in talks to join the cast of Iron Man 3.

According to Deadline, “the role is a sexy scientist every bit as smart as Tony Stark.” Chastain was previously in talks for the role, but scheduling difficulties forced her to back out. Apparently those issues have since been dealt with, and negotiations are back on.

Diane Kruger (Troy), Gemma Arterton (Quantum of Solace), and Isla Fisher (Wedding Crashers) are believed to be among the other actresses in consideration. Chastain would join the returning cast of Robert Downey Jr., Gwyneth Paltrow, and Don Cheadle, as well as Guy Pearce (Memento) and Sir Ben Kingsley (Hugo) in the Shane Black (Kiss Kiss Bang Bang) directed film. Are you happy with the casting?
