* AnticlimaxBoss: The governor. [[ImplacableMan Reza on the other hand]]...
* SugarWiki/AwesomeMusic: Music/EnnioMorricone at his usual finest throughout--albeit with a rather "trippy" twist. It's worth noting the score has often received more recognition than the actual movie.
* CompleteMonster: {{Colonel|Badass}} GŁnther "Gutierez" [[TheHeavy Reza]] is a [[SilentAntagonist silent villain]] who, throughout the movie, doesn't express a single emotion beyond self-satisfaction. He [[ColdBloodedTorture tortures Dr. Villega]] into identifying various members of a crowd as revolutionaries, then has them shot in front of him, smiling a little wider with each body that hits the ground. He's also the man responsible for the deaths of Juan's children and father, singlehandedly [[KnightOfCerebus causes the film to shift]] from BlackComedy to serious drama, leads an army ([[ANaziByAnyOtherName based on Italian fascist stormtroopers]]) that seems intent on [[SociopathicSoldier killing or imprisoning everyone they meet]], and in the climax, guns down [[spoiler:Mallory]] [[InTheBack from behind]]. This, coupled with his ImplacableMan status makes him utterly terrifying.
* CounterpartComparison: Juan and Max Lozoya from ''Don't Turn the Other Cheek'', which came out the same year. Both become revolutionary heroes and [[spoiler:both had their families killed by soldiers.]]
* EarWorm: "Sean-Sean...Sean-Sean..."
* EndingFatigue
* MoralEventHorizon: Colonel Reza and the Mexican army cross it with the [[spoiler:murder of Juan's children.]]
* {{Narm}}: Despite EnnioMorricone delivering his typical AwesomeMusic...the "Sean-Sean" song can ''really'' ruin the moment with just how ''trippy'' it is!
* OvershadowedByAwesome: Has the misfortune of falling in between two of Leone's most celebrated films.
* WhatCouldhaveBeen: Eli Wallach was originally meant to play Juan, but United Artists wanted a bigger name, so they got Rod Steiger. Some foreign dubbing companies caught wind of this during the release of 'Don't Turn the Other Cheek' and had the same foreign actors voice both Steiger's Juan and Wallach's Max.
