What happens when a Russian energy drink and a hot tub’s control panel meet? You’ll find out in “Hot Tub Time Machine,” a movie with a name that tells it all. This movie will keep audiences in stitches, even during the few saccharin moments.

What starts out as a therapeutic retreat for an at-risk friend ends up being a crazy trip down memory lane for three middle-aged men and an adventure for one barely-legal boy. Lou (Rob Coddry) finds himself plagued by the same belligerent ski patrolman as 20 years before. Adam (John Cusack) meets the love of his life, a woman he never got over. Nick (Craig Robinson) wrestles with the prospect of cheating on his wife. And Adam’s nephew, Jacob (Clark Duke), gets to experience the 1980s for the first time.
