Watch this hilarious trailer for the new comedy Hot Tub Time Machine, starring John Cusack. The film follows four losers who get together for a raunchy ski trip in which they scope out babes, try to hire a hooker and spend a crazy night drinking. When they kick back in a hot tube, they go back to 1986, where they meet their former selves — one even runs into his formerly skanky mom. Warning: adult themes and vulgar language. This clip is restricted to viewers 18 and over.
