Hot Tub Time Machine has just come out in the US and will hit our cinema screens on May 7. Four friends discover a time machine powered by a hot tub, and travel back to the 1980s for a chance to change their less than satisfactory lives. It's a silly movie, and the whole cast are in on the joke — as you can see from Craig Robinson's look to camera in the trailer. The cast is headed up by John Cusack, with Chevy Chase, Lizzy Caplan, Clark Duke and Rob Corddry. Check out the trailer and let me know if you'll see it or skip it in May!
