She'll star in Lynn Shelton's latest
Writer-helmer-producer Duplass (“Cyrus,” “Baghead”) starred in Shelton’s film “Humpday,” the 2009 indie that also incorporated improvisation.
In the untitled new project, Duplass plays a man who comes between the two sisters to be played by DeWitt and Blunt.
DeWitt next stars in “Company Men” opposite Ben Affleck and “Earthbound” with Kate Hudson, out next spring. She is also currently starring on “United States of Tara.”
