Hot Tub Time Machine is a time travel themed comedy starring John Cusack, Rob Corddry, Craig Robinson and Clark Duke, with appearances by Crispin Glover and Chevy Chase. In the film, the main characters travel back in time (via hot tub) to 1986, a simpler time filled with neon clothing, cassette tapes and cocaine. Our heroes attempt to navigate the past and find their way back to the present, while trying to avoid creating any potentially harmful time paradoxes. Also, there's a scene where someone projectile vomits on a squirrel. If there's a better time travel themed comedy out there that uses a hot tub as a plot device, I haven't seen it.
