Ewan McGregor will play a college professor once married to Roberts' character in "August: Osage County"
Meryl Streep and Julia Roberts have already signed on to star in the film, in which McGregor will play Bill Fordham. Fordham is the estranged husband of Barbara (Roberts) and son-in-law of Violet Weston (Streep).
The play, written by Tracy Letts, chronicles the women of the Weston family, who, after years apart, come together for a family crisis.
McGregor was last seen in “Salmon Fishing in The Yemen” and “Beginners,” and will next appear in Juan Antonio Bayona’s “The Impossible.” He’s also set to star in “Jack the Giant Killer,” Bryan Singer’s revisionist take on “Jack and the Beanstalk.”
