* AwesomeMusic: Music/ElmerBernstein's score, particularly the unforgettable [[http://www.youtube.com/watch?v=9iteRKvRKFA main title theme]].
** Eli Wallach (who portrayed the bandit leader Calvera) once remarked that if he'd have heard Elmer's music during filming, he'd have ridden his horse better.
* CanonForeigner: Of all the characters, Lee is the only one who isn't directly adapted from ''Film/SevenSamurai'' (instead filling the space left open by combining Kikuchiyo and Katsushiro into [[CompositeCharacter Chico]]). His characterization as a fighter who's lost his nerve would have been unbecoming of any samurai.
* CrowningMomentOfAwesome: Plenty of them.
** Britt's introduction. Also Chris and Vin's, though Britt's is even more awesome.
** The entire first confrontation with Calvera and his men. It's also one of the most quotable scene in the film ("We deal in lead, friend" amongst them).
* CrowningMomentOfFunny: This exchange, taking place just after Britt has shot dead one of the bandits who was fleeing on horseback:
-->'''Chico:''' ''[awed]'' That was the greatest shot I've ever seen!
-->'''Britt:''' ''[sternly]'' The worst! I was aiming at the ''horse''.
* FountainOfMemes: There are many [[MemeticMutation memetic lines]] from the film, and many of them occur in a five-minute sequence during the first confrontation between Calvera's bandits and the Seven. Outside of that part, there's Britt's famous "I was aiming for the horse!" and Chris' "Enemies? None.. left alive" speech.
* RepurposedPopSong: The title theme's main riff is widely known for its later use in [[http://www.youtube.com/watch?v=yQmpqvoEpws Marlboro cigarette]] commercials and Arthur Conley's 1968 hit "[[http://www.youtube.com/watch?v=grE0lwTsSPg Sweel Soul Music]]".
** In Australia, a [[SuspiciouslySimilarSong knockoff of the tune]] was famously used for [[http://www.youtube.com/watch?v=nszIJDswTBM Victoria Bitter]] ads.
* StopHelpingMe: Bernardo's Instant Fanclub follows him everywhere and tries to help him in any way; [[spoiler: they get him killed in the final battle when they distract him during a gunfight]].
* WTHCastingAgency: Yul Brynner as a Cajun and Eli Wallach as a Mexican. But both are so awesome that it's not that big of an issue.
