Rosemarie DeWitt is apparently set to star alongside Matt Damon in Gus Van Sant's upcoming drama Promised Land.
The Rachel Getting Married actress will join Matt and John Krasinski, who also co-wrote the script together, reported Deadline.
Matt and John are already on board to play rival sales executives, but there are no details as to what role Rosemarie will take.
Frances McDormand is also listed as part of the cast, although there is no further information about her part either.
Filming is set to begin in April.
Rosemarie - who starred opposite Anne Hathaway in the 2008 drama Rachel Getting Married - next stars with Emily Blunt in the drama Your Sister's Sister.
The 37-year-old will also appear in comedy Neighbourhood Watch alongside Ben Stiller, Vince Vaughn, Jonah Hill and Richard Ayoade, and fantasy drama The Odd Life Of Timothy Green with Jennifer Garner and Ron Livingstone.
