Kind of amazing that Hot Tub Time Machine got a sequel in the first place, isn't it? The sleeper/cult sci-fi comedy from 2010 got most of the cast back except for arguably, the most important member in John Cusack. Think that'll hurt the movie? Hard to tell. It looks pretty nutty and since it's the same director and writer as the first one, it'll probably be more or less what fans of the first want to see again. It's coming out on Christmas Day.
