Comedy starring Adam Sandler as a pair of twins whose annual Thanksgiving get together never fails to cause havoc. Jack Sadelstein (Sandler) appears to have everything a man could desire. A high-powered advertising executive, his successful career is augmented by a happy life at home with his wife, Erin (Katie Holmes), and their children. The one strain on Jack's happiness is his relationship with his twin sister, Jill (also Sandler), whose disconcerting combination of clinginess and passive-aggression almost always causes trouble when they meet. When Jill arrives for Thanksgiving things seem bad enough, but when she mentions that she doesn't plan on leaving the sibling warfare threatens to reach unprecedented levels. The film also features guest cameos from Al Pacino and Johnny Depp.
