* AwesomeDearBoy: Creator/RyanReynolds would ''not stop'' auditioning for superhero movies and talking himself up as the perfect casting choice for any superhero you could shake a stick at. He clearly wanted to be a superhero so very badly, and got to be Deadpool for his persistence.
* CowboyBebopAtHisComputer: A review in ''The Straits Times'' states that Logan is American, when he is really Canadian.
* CreatorBacklash: Hugh Jackman himself [[http://insidemovies.ew.com/2013/06/01/hugh-jackman-first-wolverine/ expressed regret over this film]], admitting it fell short of his expectations. Subsequently he and the rest of the crew sought to do a better job with ''The Wolverine''.
* ExecutiveMeddling:
** The Fox executives decided that it would be a '''brilliant''' idea to take {{Deadpool}}, the Merc with the Mouth and possibly one of the most popular characters appearing in the movie, introduce him and then remove him quickly, and then ''sew his mouth shut''. Because he would be too entertaining and take attention away from Wolverine or something (no-one knows the exact reason).
** Director Gavin Hood and top Fox executive Tom Rothman reportedly had clashes over the film's creative direction. One infamous incident happened while Hood was off-set, at which point Rothman took it upon himself to have one of the sets repainted from Hood's original DarkerAndEdgier theme into something more LighterAndSofter.
** Hood has also stated that the scripting process was a mess, and that portions of the screenplay were hastily rewritten ''as the movie was filming''.
* FanNickname: Dudepeel: {{Imageboards}} nickname for {{Deadpool}} InNameOnly.
** Also "[[MortalKombat Barakapool]]" because of the swords in the arms.
* FranchiseKiller: The film was a brief Franchise Killer for the ''X-Men'' movies, since it was intended to take the franchise in a different direction following the original trilogy, but the terrible reaction to it killed these plans and a different (and much more successful) direction was chosen in the semi-reboot ''Film/XMenFirstClass''.
* HeyItsThatGuy: Creator/KevinDurand as mean but dumb Blob.
* MoneyDearBoy: Creator/LievSchreiberís decision to appear in the film probably had a lot to do with the birth of his two sons.
* OldShame: HughJackman isn't proud of the film, as he felt it did little justice to his character despite the high praise he received for his performance in an otherwise underwhelming movie; he helped make up for it with ''Film/TheWolverine''.
* TheOtherDarrin:
** Tyler Mane played Sabretooth in ''Film/XMen1''. He was replaced by Creator/LievSchreiber for this movie
** Also, Stryker was played by Creator/BrianCox in ''Film/X2XMenUnited'', and by TimeshiftedActor Danny Huston here.
* PromotedFanboy: Will.i.am was a fan of the X-Men franchise who identified Nightcrawler as his favorite character and was subsequently cast to play a mutant with similar teleporting powers.
* StillbornFranchise: This movie was intended to be the first installment of an ''X-Men Origins'' film series [[{{Spinoff}} spun off]] from Fox's ''Film/XMen'' films, to be followed by ''[[WhatCouldHaveBeen X-Men Origins: Magneto]]''. After disappointing reviews for ''Wolverine'', the ''Magneto'' script was eventually incorporated into the much better-received ''Film/XMenFirstClass'' and the ''X-Men Origins'' series was scrapped.
* TroubledProduction: The film was delayed by weather and HughJackman's commitments with ''Film/{{Australia}}'', begun with an unfinished screenplay - director Gavin Hood detailed that during shooting in Australia, script pages would be sent from LA, at times in the night prior to them being filmed - and saw director Gavin Hood entering conflicts with studio 20th Century Fox, with Richard Donner (husband of producer Lauren Shuler Donner) being forced to join production to mellow out things. And an incomplete version with missing special effects leaked online one month before the film's premiere.
* This film marked Creator/HughJackman and Creator/PatrickStewart's fourth outings as Wolverine and Professor X, tying the then-record portraying a superhero held by [[Film/{{Superman}} Christopher Reeve]]. Currently Jackman is isolated with seven as of ''XMenDaysOfFuturePast'', followed by six appearances by Stewart[[note]]in ''Film/XMenFirstClass'', both Wolverine and Xavier are featured, but Xavier was played by Creator/JamesMcAvoy[[/note]] and five appearances for Creator/RobertDowneyJr as IronMan[[note]]three ''Film/IronMan'' movies, plus ''Film/TheAvengers'', and a similar cameo to Wolverine's in ''Film/TheIncredibleHulk'' [[HilariousInHindsight that also involves a dingy bar!]][[/note]] with has a sixth up ahead (''Film/TheAvengersAgeOfUltron'').
