The first poster for the R-rated comedy Hot Tub Time Machine has been released and it's after the jump.  Starring John Cusack, Rob Corddry, Craig Robinson and Clark Duke, based on the trailers, HTTM looks like it could be a really funny comedy.   Here's the synopsis:

A group of best friends have become bored with their adult lives: Adam has been dumped by his girlfriend; Lou is a party guy who can't find the party; Nick's wife controls his every move; and video game-obsessed Jacob won't leave his basement. After a crazy night of drinking in a ski resort hot tub, the men wake up, heads pounding, in the year 1986. This is their chance to kick some past and change their futures - one will find a new love life, one will learn to stand up for himself with the ladies, one will find his mojo, and one will make sure he still exists!

Look for a lot more on this movie soon:

Thanks to EW for the poster.
