* BannedInChina: Literally. Despite celebrating Ang Lee's oscar-winning movie as a triumph for the Chinese, the movie is still banned there for its portrayal of homosexuals.
* BeamMeUpScotty: The film's SignatureLine is "I wish I ''knew how to'' quit you.", not "I wish I could quit you." or "I can't quit you.".
* CreatorBacklash: [[http://leegoldberg.typepad.com/a_writers_life/2008/10/fanfic-makes-proulx-regret-writing-brokeback-mountain.html Annie Proulx has expressed regret over the story]], if only for fans who send "[[FanFic ghastly manuscripts]] and [[RuleThirtyFour pornish rewrites]] of the story to me, expecting me to reply with praise and applause for [[FixFic 'fixing' the story...]]".
* EnforcedMethodActing: In order to get into character and really show Alma's anguish over Ennis's infidelity with Jack, Creator/MichelleWilliams asked HeathLedger, who she was dating at the time, and JakeGyllenhaal to make out behind the camera so her emotional anguish would be realistic. When they weren't passionate enough, she yelled at them.
* FakeAmerican: Heath Ledger (Australian) as Ennis.
* HeyItsThatGuy: DonnieDarko turned into a cowboy?
* HeyItsThatVoice: The Japanese dub is practically a reunion of many regulars from the Franchise/{{Gundam}} franchise:
** Ennis [[Creator/ToshiyukiMorikawa is]] [[Anime/AfterWarGundamX Shagia Frost]] and [[VideoGame/SuperRobotWarsOriginalGeneration Kyosuke Nanbu]]. Also counts as a CastingGag, since Morikawa is better known for participating in many Shonen-Ai or Yaoi titles.
** Jack [[Creator/HirokiTochi is]] [[Anime/MobileSuitGundam00 Lasse Aion]] and [[Anime/MobileSuitGundamAGE Grodek Ainoa]]
** Alma Jr. (teen) [[Creator/AyumiTsunematsu is]] [[Anime/MobileSuitGundam00 Marina Ismail]] and her childhood self [[Creator/EmiriKatou is]] [[Manga/LuckyStar Kagami Hiiragi]] and [[Anime/PuellaMagiMadokaMagica Kyubey]].
** Lureen [[YukoKaida is]] [[Anime/MobileSuitGundamUnicorn Marida Cruz]], [[QueensBlade Risty]] and [[IkkiTousen Ryomu Shimei]]
* PlayingAgainstType: Creator/AnneHathaway as Lureen; this was one of several roles that moved her away from the ContractualPurity reputation she had at the time.
