Hot Tub Time Machine is a 2010 American science fiction comedy film directed by Steve Pink. Four men, all of them bored with their adult lives, travel back to their 1980s teen-hood, courtesy of a time-shifting hot tub. It stars John Cusack, Craig Robinson, Clark Duke, Kellee Stewart, Rob Corddry, Crystal Lowe, Lizzy Caplan, and Collette Wolfe. The film also features stars from 1980s films such as Chevy Chase, Billy Zabka and Crispin Glover.
The film opens in Los Angeles in the year 2010, where three friends are shown to be dissatisfied with their lives. Adam Yates' (John Cusack) obsessive-compulsive behavior has led yet another girlfriend to move out - an event missed by his geeky nephew Jacob (Clark Duke), the son of Adam's alcoholic sister who does not know who his father is and spends all of his time in Adam's basement, playing Second Life.
