Luke Wilson and Maya Rudolph are supposed to be frozen for a year, but it turns into 500. Dax Shepard is Frito, the dummy they meet who tries to help them get home. Luke goes from being a criminal to being president (taking over from a pro wrestler). Also there’s a monster truck gladiator match, a big clock in the middle of town that blinks 12:00, and some other stuff that’s too tiring to try to remember right now. A pretty okay movie with scattered funny + clever parts, not the cult classic the AV Club seems to think it has/will become.
2015 edit: I was wrong. Cult classic!
2017 edit: Watched this again, for the final time, now that it has mostly come true.
