''O'' is a 2001 adaptation of Creator/WilliamShakespeare's ''Theatre/{{Othello}}'' [[SettingUpdate set]] [[HighSchoolAU in high school]]. [[TropesAreNotBad It's better than it sounds]].

Odin (Mekhi Phifer) is the only black student at Palmetto Grove, where he is also the star basketball player, with hopes of reaching the NBA. His best friend, Hugo (Creator/JoshHartnett), is jealous of Odin's success and attempts to ruin him by making him believe that his girlfriend Desi (Creator/JuliaStiles) is carrying on an affair. It gets worse.
!!''O'' offers examples of:

* AdaptationNameChange: Done in such a way that the names are still recognizable if you're familiar with the original play (Othello is Odin, Iago is Hugo, etc). Cassio's first name was Michael in the original anyway, so he gets to keep his full name.
* AxesAtSchool: Not exactly, but close enough that it made people uncomfortable.
* BookEnds: Hugo's speech about hawks opens and closes the film.
* ButtMonkey: Roger is nothing more than Hugo's lackey.
* TheChessmaster: Hugo, as befits an update of Iago.
* CrazyJealousGuy: As befitting an adaptation of the UrExample.
* DownerEnding: [[spoiler:Fairly close to the original Shakespeare play as Odin kills Desi, then himself. Hugo gets taken into police custody, but this is going to make him famous.]]
* DrivenToSuicide: [[spoiler:O kills himself after murdering Desi and realizing he was set up by Hugo.]]
* DrugsAreBad: Hugo is addicted to steroids.
* ForTheEvulz: Downplayed from the original play in which Iago's motivations were far more ambiguous and shifted often. Here, Hugo's jealousy seems more genuine on account of his father paying more attention to Odin.
* FreudianExcuse: Hugo is made much more sympathetic (though still an obvious bad guy) in this adaptation thanks to his father's extreme preference for Odin over his own son.
* HighSchoolAU: To ''Othello'', which got the movie in trouble, thanks to Columbine.
* JerkJock: Michael often bullies Roger.
* MakeItLookLikeAnAccident: The plan is for Hugo to kill Michael and Odin to kill Desi with the intention of making it look like a murder-suicide between them. [[spoiler:The plan goes awry when Hugo's friend Roger shoots Michael in the leg, making it obvious that someone else had shot him.]]
* PragmaticAdaptation: All things considered, it's a fairly faithful adaptation of the original play. It's a testament to Shakespeare how well it still holds up.
* RaceLift: 'Moor' in Shakespeare's day could refer to several different races from Arabs to tanned Caucasians, but modern pop culture imagines Othello as a black man. So here he's an African-American.
* OneWomanWail: Played over the "all my life I always wanted to fly" scene near the end.
* QuestionableConsent: Desi and Odin's first sexual encounter starts off normally, but when he hallucinates an image of Michael having sex with her in the mirror, out of rage and jealousy, he gets rougher, prompting her to cry out and beg him to stop. He doesn't.
* ScaryBlackMan: Odin has this reputation at school and on the basketball court despite not being one. [[spoiler:He evolves into one thanks to Hugo's actions.]]
* ShoutOut: The Bard himself is referenced early on.
* SlutShaming: Michael invokes this DoubleStandard by making fun of Brandy, the girl he is sleeping with, behind her back, calling her a slut.
* ThirdActMisunderstanding: Hugo distorts a conversation that he and Michael have to prove to a hidden Odin that Michael and Desi are having sex.
* WellDoneSonGuy: Hugo's father is this, often spending more time with Odin than his own son.
