[[caption-width-right:350:Those aren't [[LoadsAndLoadsOfCharacters even all the main characters]].]]

Released just before [[TitleDrop Valentine's Day]] [[FilmsOfThe2010s 2010]], the film boasts an AllStarCast consisting of JuliaRoberts, Jamie Foxx, Creator/JessicaBiel, Creator/JessicaAlba, Creator/BradleyCooper, TaylorSwift, Hector Elizondo, Ashton Kutcher, Queen Latifah, Creator/KathyBates, Creator/JenniferGarner, and [[LoadsAndLoadsOfCharacters many, many more]]. Basically, the film follows the intersecting events of various characters, all taking place on the titular day. There's Reed (Ashton Kutcher), the hopelessly romantic florist proposing to his girlfriend (Jessica Alba). There's Julia (Garner), head-over-heels for a handsome doctor (Patrick Dempsey). Jason's (Topher Grace) just starting to fall for his new girlfriend, Liz (Creator/AnneHathaway). Meanwhile Edison (Bryce Robinson) has a crush on a girl at school. His grandparents, Edgar (Elizondo) and Estelle (Creator/ShirleyMacLaine) are getting ready to renew their vows. Kara (Biel) has sworn off love, while Sean Jackson (Eric Dane) is facing the end of a relationship and possibly the end of his career.

Nobody's Valentine's quite goes as planned. The flowers don't always reach their intended target, some relationships end, but others [[IncrediblyLamePun blossom]]. The film also does a good job of weaving the various plots together, and while not all the stories overlap, they form an overall mosaic much the same as the earlier ''LoveActually.'' Has a {{Sequel}}[=/=]SpiritualSuccessor, ''New Year's Eve'', released in 2011.

The movie definitely veers into chick flick territory, but the all-star actors give credible performances to prevent it from becoming too [[TastesLikeDiabetes saccharine]]. The film's various allusions to its actors and its awareness of various RomCom tropes make it highly enjoyable.

!!This film provides examples of:

* ActorAllusion: Dempsey plays a successful [[spoiler: (and two-timing)]] [[GreysAnatomy surgeon]]
** When Topher Grace questions the ringtone of his girlfriend, thinking it sounds techno, she says it's more retro, very [[That70sShow '70s]].
** Lautner's Willy: "I'm not really comfortable taking my shirt off in public." Possibly the funniest line in the movie for Twilight fans. (Or anti-fans, we're really not picky.)
** The limo driver asks Julia Roberts if she'd ever shopped on Rodeo Drive. [[PrettyWoman The answer?]] "Big mistake. Huge."
** A flight attendant on the airplane Julia Roberts and Bradley Cooper are flying on announces that the weather in Los Angeles has cleared up after "three days of rain" (the title of a play that Cooper and Roberts had starred in together on Broadway).
* AdvertisedExtra: Good lord, TaylorSwift and TaylorLautner. A huge chunk of the advertising for this movie had "starring Taylor Swift and Taylor Lautner" and a good chunk of the time didn't even mention any of the other actors in the film (and their then RealLife romance didn't help matters). The two have maybe three scenes in the film and are pretty extraneous.
* TheBeautifulElite: Nearly everyone in the huge cast is absurdly pretty.
* BigDamnKiss:
** Reed (Kutcher) and Julia (Garner) try for this. [[SubvertedTrope It ends up being really awkward.]] But then they talk about it and try again, and this time [[DoublySubverted the music swells.]]
** Kara (Biel) and Kelvin (Foxx) gets one because they were kissing in front of a Green Screen, [[InvokedTrope and Kelvin's coworkers changed the background to a sunset.]]
* ButNotTooGay: [[spoiler: Sean (Dane) and Holden (Cooper) never kiss, even though nearly all of the other couples, including the teenagers, do]].
* TheCameo: Yes, that's Joe Mantegna who almost gets hit by Kutcher's van
* CastingGag: Creator/EmmaRoberts as the babysitter of [[spoiler:Creator/JuliaRoberts's]] character's son.
* DuetBonding: Kara (Biel) and Kelvin (Jamie Foxx) get one to the tune of "I Will Survive"
* DumbBlonde: Felicia, as played by Taylor Swift, and almost certainly a dig at the way some of the media view her
* HighSchoolSweethearts: Grace and Alex
** Felicia and Willy parody the concept
-->'''Male Anchor:''' There you have it, folks. Young love. Full of promise, full of hope, ignorant of reality.
* HilariousInHindsight: Sean coming out as he prepares for free agency is oddly similar to basketball player Jason Collins.
* JustFriends: Reed and Julia start out this way.
* [[MagicalNegro Magical Latino]]: George Lopez's character
* TheNotLoveInterest: You would think Bradley Cooper and JuliaRoberts's characters would get to get together. He's actually [[spoiler: Sean Jackson's boyfriend]]
* OneSteveLimit: Subverted with the cast which consists of two Roberts (Julia Roberts and her niece Emma), two Jessicas (Alba and Biel), and two Taylors (Swift and Lautner), but averted with two Christophers in which neither actor professionally goes by his real first name (Ashton Kutcher and Topher Grace).
** The outtakes at the end poke fun at the Taylor and Taylor pairing.
--> '''Swift''': Hey, I'm Taylor.
--> '''Lautner''': and I'm Taylor.
--> '''Swift''': Yeah it's confusing.
--> '''Lautner''': *Laughs*
--> '''Swift''': yeah we know that.
* PrecociousCrush: [[spoiler:Edison]]
* {{Sequel}} / {{Sequelitis}}: Has its own sequel, ''New Year's Eve''.
* SpiritualSuccessor: To ''LoveActually''.
* StraightGay: [[spoiler: Football player Sean Jackson]]
** [[spoiler: And his love interest, Bradley Cooper]], culminating in their getting back together.
* TalentBomb: You can almost hear the fuse...
* TeacherStudentRomance: [[spoiler:Edison for Julia]]. Unrequited, of course, and she redirects him toward [[spoiler:Rani]].
* YourCheatingHeart
