Filmmakers Peter and Bobby Farrelly The two brothers have become practically the brand name for bad taste. Their movies Dumb and Dumber, Kingpin, There's Something About Mary and Shallow Hall, plumbed new depths of tastelessness. But their fans love the films, and despite their gross-out humor, the Farrellys seem to create characters that audiences care about. Their new film Stuck on You is about two brothers who are Siamese twins. It stars Matt Damon and Greg Kinnear. It's supposedly their most autobiographical film.
