American Beauty star Mena Suvari has joined the growing cast of Dodgeball director Rawson Thurber's new movie The Mysteries of Pittsburgh. She joins Peter Sarsgaard, Sienna Miller and Jon Foster in the the movie which is an adaptation of Michael Chabon's Pulitzer Prize winning novel. Some plot info from Dark Horizons... "Set in industrial Pittsburgh in the mid-eighties, the story chronicles the last summer of Art Bechstein's (Foster) youth. Art meets the witty and beautiful Arthur Lecomte, who then introduces Art to the equally stunning Jane (Sienna Miller), her boyfriend, the legendary Cleveland (Peter Sarsgaard), and worldly, exotic and slightly eccentric Phlox (Suvari)"."In the course of one summer, this band of colorful friends guides and thwarts Art in surprising ways as he confronts himself, his family, his sexuality and the heartache of growing up". Sounds like it could be a lot of fun and could be the next Garden State. And the cast looks great too! source - production weekly, dark horizons
