Sienna Miller has reportedly joined the cast of upcoming drama Foxcatcher.
The Factory Girl actress - who welcomed her first child, daughter Marlowe, in July - will play the wife of tragic Olympic wrestler Dave Schultz in the film, which is based on a true story, according to Deadline.
Steve Carell is tipped to play John du Pont, heir to the du Pont chemical fortune, who built a wrestling training centre called Team Foxcatcher. He shot and killed his friend Schultz during an attack of paranoid schizophrenia.
Foxcatcher will be directed by Bennett Miller.
