Frownland is a 2007 American independent film written and directed by Ronald Bronstein. It stars Dore Mann as Keith, a self-described "troll", who sweats and stutters his way through his job as a door-to-door salesman, dubiously selling coupons to assist people affected by multiple sclerosis. The film is populated by a cast of characters as dysfunctional and full of neuroses as Keith. The title comes from the song "Frownland" off the album Trout Mask Replica, by Captain Beefheart (who suffered from multiple sclerosis).
