The project also boasts some other big names.

John Krasinski (“The Office”) and Rosemarie DeWitt (“Mad Men,” “United States of Tara”) have signed on to the film. Director Gus Van Sant, who shot “Good Will Hunting,” “Milk” and “Finding Forrester,” has signed on to direct the film, which is in pre-production, according to IMDB.

Filming is slated to begin in the Pittsburgh area later this month and run through early June, according to the Pittsburgh Film Office. The film is holding a casting call in Pittsburgh on Saturday to fill parts for “great character faces, farmer looks, senior citizens, baseball players, upscale men and women with formal wear, teens and kids.”

Damon also co-wrote the film and Van Sant’s inclusion assures it will at least be an interesting film.
