''Om Shanti Om'' is a 2007 UsefulNotes/{{Bollywood}} film directed and choreographed by Farah Khan. It stars Creator/ShahRukhKhan and Deepika Padukone in the lead roles as the protagonists while Shreyas Talpade, Arjun Rampal, and Kirron Kher feature in supporting roles. Arjun Rampal is the BigBad in the movie. More than forty two well-known Bollywood stars appear in the course of the film, including thirty of them (not including the stars of the film) in one song alone.

Protagonist Om Prakash Makhija (Shah Rukh Khan) is a junior artist in the 1970s film industry. He and his friend Pappu (Shreyas Talpade) are trying to succeed as leading actors. Om's mother, Bela Makhija (Kirron Kher), herself a junior artist, inspires and encourages her son to become a success. He is in love with the film actress Shanti Priya (Deepika Padukone), whom he eventually befriends after saving her from a fire in set. He tries to confess his feelings to her, but he gets overwhelmed by Shanti's true kindness and decides to wait for a better chance.

One day, Om tries to talk to Shanti on the set of a film, but is almost ignored. He follows her into a dressing-room, where he, unseen except by the viewer, overhears her argument with the film's producer Mukesh Mehra (Arjun Rampal) about a recent promise of Mukesh's to marry a businessman's daughter in return for funding of a film. It is here revealed that Shanti is secretly married to Mukesh, and that Shanti is pregnant with Mukesh's child. Mukesh insists that his relationship with Shanti be kept secret, arguing that its revelation will spoil his plans and her career; but Shanti demands that they marry in public. Mukesh relents when she reveals her pregnancy. Om leaves, disappointed, and remains miserable for some days.

Unfortunately. Mukesh doesn't really want to stay married to Shanti, and tricks her into entering in a soundstage with the excuse of talking about their next movie and wedding. He then traps her on set and then sets the place in fire. Om, after seeing this, tries in vain to rescue her, and he ends badly burnt and run over by actor Rajesh Kapoor, who was carrying his soon-to-have-birth wife to the hospital. Kapoor carries them both to the hospital, but as his wife gives birth, Om dies from all his injuries.

The plot then moves 30 years and we meet Om Kapur (also played by Shah Rukh Khan), the son of Rajesh Kapoor and the reincarnation of Om Prakash. Om Kapur, nicknamed OK, is a very popular and talented leading actor, but also a very bratty one, accustomed to always getting his way. Strangely, he has pyrophobia despite never having bad experiences with fire. A chance encounter with Mukesh (now a successful international movie producer) and the discovery of the remains of the studios where Shanti died awakens the memories of his former life.

Furious for the fact that neither his past life's nor Shanti's deaths received justice, OK decides to make Mukesh confess his crimes. His plan is simple: revive the production of the movie Shanti was going to star in, had Mukesh not killed her, then having someone masquerading as her roaming the studio to spook Mukesh until he breaks and confess on tape. OK even has the very good luck of finding a dead-on Shanti lookalike in one of his fangirls; but even with that help, making Mukesh nervous enough to confess is easier said than done...

* BigNo: Om Prakash's mom shouts a big "Nahin!" when she hears he wants to change his name.
* BirthDeathJuxtaposition: When [[spoiler:Om]] dies in the hospital, a mother gives birth in the next room. [[spoiler:The baby turns out to be Om reincarnated.]]
* CreatorCameo: Farah Khan is the woman who fights with Om Prakash at the beginning of the movie. Lampshaded:
---> '''Farah Khan:''' Hey, who do you think you are, the star of the movie?
---> '''Om Prakash:''' Well, who do you think ''you'' are, the director?
* CrowdSong: Obviously since it's Bollywood.
* DeathByLookingUp: [[spoiler: Mukesh]].
* DoNotCallMePaul: Mukesh insists on being called Mike, because that's what they call him in Hollywood.
* DreamSequence: How OK convinces the director to change the planned scene to the [[ShirtlessScene Dar De Disco]] [[TheItemNumber number]].
* EngineeredPublicConfession: [[spoiler: Om's plan to get Mukesh arrested for Shanti's murder]].
* EpicRocking: Dastaan-E-Om Shanti Om
* FallingChandelierOfDoom: [[spoiler:Mukesh]] suffers this fate in the end. [[AndThereWasMuchRejoicing Everyone in the theatre celebrated]].
* {{Fangirl}}: Sandhya for Om. And Om for Shantipriya.
* FanNickname: In-Universe example: Om Kapoor's fans call him OK.
* {{Fan Service}} Major example: OK in Dard E Disco (Usually an Item Number has an Item Girl. This one has an Item Guy instead.)
* FlashBackEcho: Triggered by the discovery of the old movie studios.
* GratuitousEnglish
* HoistByHisOwnPetard: [[spoiler:Mukesh.]]
* LargeHam: Om Prakash and OK are pretty much this.
* LoveAtFirstSight
* MasqueradeBall: ''Dastaan-E-Om Shanti Om''.
* MeetCute: Shanti's sari gets caught on Om's bracelet.
* NoCelebritiesWereHarmed: Rajesh and Lovely Kapoor are probably parodies of Creator/RajeshKhanna and his wife Dimple Kapadia.
** Om Prakash and Pappu sneak in a movie theatre, pretending to be Manoj Kumar. The "real" Manoj later arrives, showing his ID with him covering his face.
*** He actually complained about the parody when the movie was released.
* {{OrangeBlueContrast}}: in most of the song Dard E Disco. (beautiful colors.)
* OscarBait: Parodied when Om has to play a blind deaf mute with no legs or arms. Sure, critics will love it but his fans will be bored.
* ParodyNames: All the movies shown at the Filmfare Awards, especially ''Phir Bhi Dil Hai NRI''.
* PosthumousCharacter: [[spoiler:Shanti.]]
* RasputinianDeath: Om is beaten down mercilessly by security guards, repeatedly. He still manages to rise up, and bursts into a burning house to save Shanti. An explosion knocks him not only away from her, but out of the building entirely and into a nearby street. And he still manages to rise up to his feet again, only to finally be mortally wounded when Rajesh Kapoor's car hits him accidentally.
* RedHerring: [[spoiler: The movie makes you think that Sandy is Shanti's reincarnation. Turns out, Shanti never reincarnated, as she becomes a vengeful ghost delivering KarmicDeath.]]
* RedStringOfFate: Literally. Bela ties a red string around her son's wrist for luck, and it leads to his MeetCute.
* [[spoiler:{{Reincarnation}}: Om is reincarnated and looks exactly like he did in his previous life, complete with his tattoo becoming some sort of birthmark.]]
* RescueRomance: Om and Shanti.
* SelfDeprecation: The actors in the movie are pretty much making fun of themselves.
* TheSeventies: The first half of the movie.
* ShirtlessScene: OK gets this a lot. Hence, [[Creator/ShahRukhKhan SRK's page image]].
* ShoutOut: Too many to count, especially in the musical numbers.
* SmugSnake: Mukesh is a real dick.
* SpoiledBrat: Om Kapoor [[spoiler: though it gets better once he remembers his past life]].
* StageMom: Kamini.
* ThatRemindsMeOfASong: At the Filmfare Awards after-party, OK's father tells him that he has a surprise for him: a musical number performed by many famous (real life) Bollywood actors and actresses. It has no relevance at all to the plot, which resumes after the song ends.
* TheItemNumber: parodied and lampshaded. Om Kapoor and the director of his movie have a discussion where OK forces the director to change the scene he is supposed to act for a disco dance number of this nature. Sure enough, immediately cues said musical number. Albeit in this case, this number has a reason of existence beside mere {{fanservice}}, since serves as a setup to show OK pyrophobia for the first time.
* TitleDrop: During the "Deewangi Deewangi" number
* UnderwearOfPower: All the superheroes of the [[IncrediblyLamePun Mohabbat Man]] movie.
* UnusualEuphemism: Oh, what the fish!
* WagTheDirector: In-universe. When Om doesn't like the scene he's supposed to play, he makes the director change it for a disco dance number.
* WellDoneSonGuy: Rajesh Kapoor.
* TheWestern: Or more precisely, the Masala Western.
* WholePlotReference: [[spoiler: OK's plot to get Mukesh to confess is similar to Hamlet's [[ShowWithinAShow Play Within A Play.]]]]
* [[WhyDidItHaveToBeSnakes Why Did It Have To Be Fire?]]: OK, no thanks to his [[spoiler:previous life's attempt to save Shanti from a burning set.]]
