I'll start by saying that Hot Tub Time Machine is a balls to the wall, all out, hard R-rated comedy that doesn't hold back for a second. It's an ode to classic 80's and time travel films with a fantastic 80's soundtrack that will make you feel like you're....well....partying in the 80's.
The film stars John Cusack, Craig Robinson, Clark Duke, and the man who stole the entire film, Rob Corddry. It's directed by Steve Pink, who also wrote the films Gross Point Blank and High Fidelity which also star John Cusack, so he knows how to work with the man and it certainly shows in this film as we see Cusacks charm flow off screen and mesmerize the audience in virtually every scene he's in. He's got one of the best voices in Hollywood, and he's one hell of a cool dude.
The film centers around the four friends retreating to a hotel at a ski mountain that they all stayed at one time during the 80's together and all experienced life changing events during that time. This time around they're trying to help out their best friend who, the night before, ended himself in the hospital from an alcohol and car exhaust overdose (an absolutely hilarious scene to start the film). Once arriving at the hotel they immediately start partying it up in the room and reminiscing a bit on the last time they were there, in the 80's. Pretty soon the hot tub starts working, they all get naked (yes four straight guys), jump in, party like maniacs, and soon get transported to the same day in the 80's when they last stayed at the hotel. From then on they have to try and play everything out exactly how it happened then, or else the hot tub time machine (god I love writing that) will not work correctly and they wont make it....back to the future. But they learn that it's not that easy and the temptations arise and hilarity ensues for the remainder of the film.
There are some hilarious cameos in the film including Chevy Chase, Crispin Glover (from Back to the Future), and William Zabka, who played Johnny from The Karate Kid. This is a party film by all means, so when you go see this in theaters or you wait to dvd or blu-ray for some dumb reason, be ready to party. Hot Tub Time Machine gets a 4 outa 5.
