* ActorAllusion: One scene features the line: "I want my two dollars!" which is a reference to ''BetterOffDead'', one of Cusack's earliest films (which also took place at a ski resort). Also on seeing all the drugs in Adam's suitcase, Jacob says "What are you, HunterSThompson?" to which Adam replies, "I thought I was." JohnCusack was close friends with Thompson, and attended his funeral. On a more meta note, Cusack had also campaigned for the role of the Thompson equivilant in FearAndLoathingInLasVegas, a role that eventually went to Johnny Depp.

* RevivalByCommercialization: The song "Home Sweet Home" by MotleyCrue received a brief boost in popularity following the release of this film.

* DoubleStandardAbuseFemaleOnMale: 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 [[spoiler: 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. If he had stabbed her in the eye for any reason besides self-defense he would be a CompleteMonster

* TheEighties: Where our protagonists end up. Everything's so exaggerated, you can't tell whether for comedic purposes or because the characters are travelling back to their half-forgotten youth.

A sequel is currently in development and is to be released sometime in 2014. The sequel will take place 10 years in the future.

* HotMom: [[spoiler:Kelly at the end of the movie, who looks way too young and attractive to have a 20 year old son.]]

* MsFanservice: Tara (the busty groupie that Nick hooks up with) and Zoe (the girl who "only does two at a time"). Both women have very roles, yet appear topless.

A sequel is currently in development and is to be released sometime in 2014.

* TheEighties: Oh yeahh.

* TheSlowPath: [[spoiler: Lou stays behind in the past to become rich and make sure that the events of this weekend propelled them into a Better Future. He suffers no ill effects because it is MentalTimeTravel]]

* [[HeavyMetalUmlaut Heävy Mëtal Ümlaut]]: [[spoiler: Mötley Lüe, Lou's multi-platinum-selling band in which he rose to fame after [[IChooseToStay deciding to stay in the past]]]].
* HeroicBastard: Jacob[[spoiler:, at least until Lou (who, it turns out, is Jacob's father) changes the past so that he and Adam's sister get married.)]]
* HeyItsThatGuy: [[Film/GrossePointeBlank Martin Blank]], [[TheOffice Darrel]], [[Series/TheDailyShow that one dude from The Daily Show]] and [[KickAss one of Dave Lizewski's friends]] travel to the 1980s and run into [[Film/BackToTheFuture George McFly]], [[TheKarateKid Johnny Lawrence]], [[Film/{{Cloverfield}} Marlena Diamond]] and [[NationalLampoonsChristmasVacation Clark Griswold]].

* ItsNotYouItsMe: Played straight, both when Adam originally broke up with his girlfriend, [[spoiler:and again in the AlternateTimeline when ''she'' dumps ''him'', which she was gonna do anyway]].
* KnightTemplar: 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 [[DirtyCommunists Red Scare]] as an excuse to be [[{{Jerkass}} Jerkasses]].

* NostalgiaFilter: 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. [[spoiler: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.]]

* NoodleIncident: Cincinnati, and "Great white buffalo."
** Based on the times its mentioned, it's hinted that "Great White Buffalo" is actually [[spoiler: April, after she moved on, had kids, and let herself go]].
