Rebecca Hall is currently in talks to replace Jessica Chastain in Iron Man 3. Chastain, who seems to have a movie coming out every month, announced that her schedule would be too busy in order to fit Iron Man in. Variety is reporting that the character Hall would play won’t be the lead of the film, but a scientist who specializes in nanotechnology, all but assuring that Iron Man 3 will follow the Extremis storyline.
Iron Man 3 will be the first Marvel movie post Avengers so it will probably have a lot of pressure on it because it will dictate where the Avengers heroes go before the recently announced sequel hits the screen. Iron Man 3 will be directed by Shane Black and arrive in theaters on May 3, 2013.
