A 2010 film directed by Steve Pink (the guy who did Accepted). Three friends (Adam, Lou and Nick), and Adam's nephew Jacob take a trip to a ski resort where Adam, Lou and Nick used to hang out to relive good times after Lou attempts suicide. However, while getting drunk in a hot tub, Lou spills some Chernobly (a type of Russian Red Bull) onto the hot tub controls, turning it into a time machine. The hot tub sends the four back to 1986, where Adam, Lou and Nick have regained their youth and replaced their 1986 selves. (Jacob, for some reason, is not a zygote. This goes unexplained, though he occasionally goes static like a television image with poor reception.)A hot-tub repairman (played by Chevy Chase), who may or may not be Mr. Exposition, occasionally drops by to have Cryptic Conversations about how to return to 2010 and the consequences of changing the past. This, however, doesn't stop the three from trying, much to the dismay of Jacob, who feels that their actions may put his very existence in jeopardy via the Butterfly Effect.The last film to be distributed by MGM before its bankruptcy and reorganization as a pure producer and co-funder.A sequel is scheduled to be released on Christmas Day, 2014. The sequel will take place 10 years in the future.
Adam: By the way, where does it say in the fucking Friendship Handbook that you are the only one who's allowed any fucking problems?
Lou: I forgot that it says in the Asshole Handbook that you can just fuck over your friends whenever you want!
Adam: Actually, it would say that in the Asshole Handbook if it was, like, guidelines for being an asshole, that's what it would say.
Artistic License - History: Contrary to what the writers would have you believe, they had snowboards back in '86. Most ski resorts still didn't allow them, but being a ski patroller, Blaine could reasonably be expected to know what one is.
As Long as It Sounds Foreign: When pretending to be a Russian spy, Nick brandishes the can of Chernobly like it was a bomb and repeatedly shouts "Dosvedanya!", which is Russian for "Goodbye" or "Farewell."
Dirty Communists: The time travelers are mistaken for these after Blaine and the ski patrol find their modern cell phones and MP3 players (which they think are spy gadgets), and their can of Chernobly.
Double Standard: Abuse, Female on Male: Jenny stabbing Adam in the eye for breaking up with her is treated fairly trivially. Despite knowing what she did Adam and his friends still think he shouldn't have broken up with her and when Adam does get angry at her its for her hypocrisy for getting mad at him when she was going to break up with him anyway not for being violent in the first place. Not once does anyone comment that stabbing someone in the eye is a despicable, abusive act.
Driven to Suicide: At the end of the film Lou confesses that he was trying to kill himself at the start of the film.
Dude, Not Funny!: In-universe. Kelly is appalled when Lou starts laughing at the Bellhop losing his arm.
The Eighties: Where our protagonists end up. Everything's so exaggerated, you can't tell whether for comedic purposes or because the characters are traveling back to their half-forgotten youth.
Nick: You know how every group of friends has that one asshole? He's our asshole.
Happily Ever After: All of the main characters have greatly-improved lives by the end of the film. Adam is married to April and lives in a big house, Nick is a successul music producer and his wife is completely faithful to him, and Lou is a happily-married billionaire.
Henpecked Husband: Nick starts out as this, becoming a hyphenate (taking his wife's last name), giving up his dream of being a musician to please her, and putting up with his wife cheating on him because he doesn't have the courage to confront her about it.
I Choose to Stay: Lou. Adam also choses to stay behind, but ends up falling into the hot tub during the return trip. Lou was probably right to do so, since the other characters don't know about their exploits between 1986 and the present day.
I'm Standing Right Here: Believing Lou to be asleep, Nick and Adam start having listing off all the reasons why Lou's life sucks and why he'd want to kill himself. Lou is not asleep, and he calls them out for it.
It's Not You, It's Me: Played straight, both when Adam originally broke up with his girlfriend, and again in the Alternate Timeline when she dumps him (which she was gonna do in the original timeline anyway).
Knight Templar: Blaine and his ski patrol friends. They have a legitimate mission of maintaining law and order on the mountain, but they use this and the Red Scare as an excuse to be Jerkasses.
Manic Pixie Dream Girl: April. Played surprisingly straight, she just appears in Adam's life, fixates on him (particularly odd, since she's apparently an established music journalist and Adam's a teenager), takes him out of the dull funk that he's in, and even engages in some low-level breaking and entering for the sake of romance.
Nostalgia Filter: At first Adam can't remember why he broke up with his old girlfriend, Jenny, and because he only recalls good things about her he believes that he made a huge mistake by dumping her. Once we actually meet her in the past and find out how shallow and crazy she is, it's not hard to see why Adam dumped her. But he was still unhappy with the whole situation.
Not Good With Rejection: In the original timeline, Jenny stabs Adam in the eye with a fork after he breaks up with her.
Pet the Dog: Blaine and his ski patrol buddies spend most of the film as complete jerkasses, but in the end they manage to redeem themselves somewhat by working quickly and professionally to save the Bellhop's arm.
Playing Gertrude: Kelly and April in the future. Kelly especially because at they tried to make April look older.
Set Right What Once Went Wrong: What the guys end up doing once they summon up the brass to defy the repairman and do things the way they wish they had. In the end it results in them all having much better lives than they did before.
Title Drop: So obvious it's Anvilicious... "It must be some kind of... Hot Tub Time Machine." Craig Robinson lampshades the trope by delivering a deadpan Aside Glance to the camera immediately after saying the line.
Trailers Always Spoil: Depending on which trailer you saw, one of them shows Violator aboard the huge yacht he bought himself after inventing Lougle, therefore spoiling the fact that he stays in the past. Nice.
Another trailer showed Jacob seeing his mother in 1986, and then shows her in bed with Lou saying "I feel pregnant."
Jacob pukes on Lou when the Bellhop's arm gets ripped off by a passing snowplow.
Weirdness Search and Rescue: The guy who fixes the hot tub and acts like he knows about time travel. However, he doesn't tell them about the time travel.
Wealthy Yacht Owner: Lou exploits his knowledge of the future to become a billionaire. At the end of the film he is seen aboard a huge yacht named Violator.
What the Hell, Hero?: After being beaten up by Blane and his friends, Lou emotionally chastises Nick and especially Adam for being piss-poor friends who are never around when he needs them. Adam argues at first, but eventually has to admit that Lou is right.
