Step Up is a film franchise. Based around dancing, mostly hip hop / breakdancing, each film follows the story of a dancer who uses their talent as a form of expression and their subsequent romance with a fellow dancer, generally from a different class background. The films are a bit of a ClicheStorm, following a pretty consistent formula particularly when it comes to the love story aspects, but the series' clear focus is on the spectacular dance numbers that grow more and more elaborate with each new installment.

There are currently five Step Up films:

Step Up (2006) follows teen delinquent Tyler (ChanningTatum in his breakout role), a talented hip-hop dancer who ends up forced to do community service at the fictional Maryland School of the Arts after he is caught vandalizing school property. However, his life changes when one of the students, UptownGirl Nora, enlists him to be her partner for her senior performance after her regular partner is injured. This first installment established the series' long-running theme of inter-class conflict, particularly in relation to the divide between hip-hop (considered "lower class") and more "traditional" dance forms like ballet or contemporary (taught at the "upper class" private arts school). It's also the darkest installment of the films, being the only one where a character dies during the course of the story.

Step Up 2: The Streets (2008) follows Andie, a tomboy from Tyler's neighborhood with her own delinquent streak who is forced to choose between attending MSA and being shipped off to Texas to live with her aunt. However, her new life at the school affects her relationship with her friends from her neighborhood, who as a dance crew are the champions of a local hip-hop dance competition known as "The Streets." After most of her old friends reject her, Andie teams up with her new friend Moose and MSA's local BigManonCampus, Chase, to put together a new crew to compete in The Streets. This film marked the series' turn towards hip-hop dancing as a primary focus rather than the balance of hip-hop and contemporary in the previous installment and introduced EnsembleDarkhorse Moose, who has featured in every film since. It is also the only film in the series to have the female lead as the primary protagonist.

Step Up 3D (2010) follows Moose from the previous film as he starts his freshman year of college at NYU, leading him to meet up with his old friend Camille (Tyler's foster sister, possibly biological sister, from the first film) as well as the film's real protagonist, Luke, leader of the House of Pirates dance crew. Luke enlists Moose as a member of his crew in preparation for the upcoming World Jam competition, where they face off against their rivals, the House of Samurai, whose leader Julien used to be friends with Luke before they had a falling out. However, problems arise when Luke discovers his teammate and love interest Natalie is not all she appears to be. As the name indicates, this was the first film in the series to be shot in 3D, with a number of sequences designed to take advantage of technology.

Step Up: Revolution, also known as Miami Heat (2012) follows Sean, the leader of the Mob, a Miami-based dance crew that stages elaborate flash-mobs. Through his day job as a hotel waiter, Sean meets Emily, the hotel owner's daughter and a contemporary dancer auditioning for a spot at a prestigious dance academy, and invites her to join the Mob. However, the group then finds out that Emily's father is planning to destroy their neighborhood, causing the group to use their flash-mobs as a form of protest art to save their homes even as their actions threaten Sean and Emily's budding romance. This film marked a return to the series' roots of blending hip-hop and contemporary dance styles, although the emphasis is still largely on hip-hop, and also has perhaps the highest amount of fanservice in any of the films.

Step Up: All In (2014) continues Sean's story as he and the Mob struggle to get by as working dancers in L.A., ultimately resulting in everyone but Sean returning to Miami. However, when Sean hears about a dance contest on VH1 for a three-year contract to perform at a hotel in Las Vegas, he enlists Moose to help him put together a new crew consisting entirely of characters from the previous films. This includes Andie, protagonist of The Streets, who had been forced to quit dancing after a knee injury and is now ready to get back in the game, although her fears of getting injured again form her subplot for the film. Naturally, tensions arise when Sean learns that the Mob has joined the competition, although the real problem is the Grim Warriors, a crew that neither group likes. This film returns to the dance battle structure of The Streets and 3D after the flash-mobs of Revolution, and is the first film in the series to feature both reoccuring male and female leads.

!! The films provide examples of:
* {{Adorkable}}: Moose from the second film has shades of this.
* AllGirlsWantBadBoys: Nora Clark falls in love with Tyler. Well, Tyler isn't ''bad'' persay, but he is very TroubledButCute.
* AllStarCast: All In features characters from the first four movies.
* AlternativeForeignThemeSong: Koda Kumi's [[http://www.youtube.com/watch?v=uGUI5Iqnuzw "But"]] is used as the theme song in the Japanese version.
* BetaCouple: Miles and Lucy in Step Up, Moose and Sophie in The Streets, Moose and Camille in 3D and All In
* CallBack: Tyler in Step Up 2 is only there for a couple of scenes to remind us that he was in the first movie. Tyler's sister Camille is brought back as a main character for the third movie
* CoolPeopleRebelAgainstAuthority: Oh so much. Specially stagnant in Step Up 2 and Revolution.
** Step Up 2: If you are an arts school alumn who insists in making your own steps whenever you are being teached some, or to breakdance in the middle of a dramatic swashbuckler scene, the big bad stablishment is guilty of not allowing you to express yourself.
** Step Up Revolution: If your father the businessman only allows you to pursue a dancing career, instead of having a more secure job that you have studied to be able to have... if you pass the very same intense test that you were already trying to pass, he is being blind to who you are and his judgement is clouded by his corporativism. Oh, and this same international businessman called on the staff of one of his hotels for a meeting. One of them arrived to the meeting twenty minutes late and untidy, didn't provide of a convincing explanation. The boss dared to fire him. [[SarcasmMode What a douche]].
* CreepyTwins: the Grim Warriors crew in All In features a pair [[spoiler: they turn out much nicer in person]]
* CrowningMomentOfAwesome: Invoked in All In. [[spoiler:Even the producers, who were about to crown Grim Knight the victors, couldn't deny that [=LMNtrix=] put in the better performance during the finals.]]
* DanceOfRomance: Of course.
* DancePartyEnding: in 2,4 and 5
* DangerouslyGenreSavvy: in All In, the group learns that [[spoiler: the contest is blatantly rigged. In response, they purposefully create a ClicheStorm winning performance that the company executives couldn't have lose without revealing the scheme]]
* DoesNotLikeShoes: Emily, from the 4th film, is barefoot in all, but two of her dance sequences, and she has ''a lot'' of dance scenes. In fact she probably is seen barefoot more often than with shoes on.
** Understandable, as Kathryn McCormick (who plays Emily) is primarily a Contemporary Ballet dancer. Many dancers in that style prefer dancing without shoes.
* DudeWheresMyRespect: The Mob fades from the headlines after Revolution and has to start from the ground up in All In
* EleventhHourRanger: The MSA Crew (minus Camille) in 3D
* FanService: some of the one-on-one dances are really sensual. Step Up Revolution ranked that UpToEleven.
* HappilyEverBefore: Andie and Chase in The Streets and Sean and Emily in Revolution. All In reveals that both pairs broke up at some point between the ends of their films and the beginning of All In, which features Sean and Andie as a couple.
* HappilyMarried: Maybe for Moose and Camille. There are several signs that they are, even though it's never explicitly stated.
* HeelFaceTurn: Mack after [[spoiler: Skinny's death]]. He wasn't exactly bad but he decides to completely give up a life of crime.
* HeyItsThatGuy: Fans of ''America's Best Dance Crew, the League of Extraordinary Dancers,'' and ''So You Think You Can Dance'' will recognize several characters in ''All In.''
* HopelessAuditionees: the Mob somehow manage to end up as such in All In
* GondorCallsForAid: the ending of Revolution
* LighterAndSofter: The first movie the main character is a car thief and one of his friends is killed in a Drive-By. The rest of the series is not as edgy.
* NiceJobBreakingItHero: The fourth film has an instance of this when Eddy, frustrated with how things were going between him and Sean, stages a MOB outing that decidedly looks more like an act of terrorism than a traditional MOB performance, which ends in the MOB being DQ'd from the YouTube competition that they were trying to win for the community. ''[[SincerityMode Dick move, Eddy.]]''
* NoodleIncident: How Camille and Moose actually met is never explained. Perhaps if Camille had been the star of the second movie...
* PotteryBarnPoor: In Step Up Revolution, the whole crew and their families and friends live in a humble Latin neighborhood, mostly as blue-collar workers. The budget needed for every one of their flash mobs goes easily into several hundred or even thousand dollars.
** In Step Up 3, they need to win the contest that they've been after for the whole movie or they won't be able to keep their only shelter, where many of them are lucky to be able to live... a whole building that contains an amazing discotheque, a first floor only for training, a wall made of boomboxes, a collection of really expensive mint-state limited edition sneakers... the guy in charge of this all? Oh, he is a waiter with a dream. The dream made everything else possible. Somehow.
* PuttingTheBandBackTogether: the Lmntrix crew in All In is made of Moose's old friends. To lesser degree in other movies: if there is a character from the previous movie in the crew, you can expect him to call his friends for the finale.
* RagtagBunchOfMisfits: several, especially the students in The Streets
* RememberTheNewGuy: Camille in 3D in treated as having been with MSA crew all along despite not being in the second movie.
** Andie, Tyler remembers the little girl that the audience doesn't.
* SeriousBusiness: Hip-hop street dancing in the second and third movies is regarded as such.
** During the second movie, Chase and the MSA crew make a untasteful but harmless prank to their rival crew's leader, something that is mentioned as a traditional way of challenging someone. The leader and a couple of guys find Chase and beat him hard.
** Somehow deconstructed in the third movie. Moose outclassed a guy from the Samurai crew. Then a group of the Samurai ambush him, and he's pressured and intimidated... but not him nor them attack each other: all their fight is breakdancing all over the place, while still being filmed like a fight scene.
* SheCleansUpNicely: Andie looks quite good in a dress
* TheReasonYouSuckSpeech: Tyler gives one to Nora after [[spoiler: she replaces him with her old partner Andrew]]
* ThirdIs3D
* ThirdActMisunderstanding: A common staple. Notably [[spoiler: Natalie being Julian's sister in 3D and Emily being Bill Anderson's daughter in Revolution/Miami Heat.]]
** [[spoiler:Not so much in 3D; Natalie was Julian's sister AND she came to the Pirates to spy them. The misunderstanding is not being believed when she declared that she had [[DefectingForLove defected for love]].]]
* ThoseTwoGuys: The Santiago Twins
* TomBoy: Andie West
* TroubledButCute: Tyler Gage
** An argument could be made for Andie as a GenderFlipped version at the beginning of The Streets prior to her CharacterDevelopment.
* UptownGirl: Nora. With Tyler as her love interest from the wrong side of town.
** This trope is the staple for all the main romances in the series: Natalie from the third movie and Emily from the upcoming fourth film are both wealthy girls who fall in love with guys of a lower socio-economic class, while Chase in the second film is a GenderFlipped version who falls for Andie, a girl from Tyler's neighborhood.
** Also subverted in All In: both the male and female leads--Sean from Revolution and Andie from the Streets--come from the same class background.
