* AwesomeDearBoy: Creator/RyanReynolds took a bit part in the movie solely so he could play [[SelfDemonstrating/{{Deadpool}} Wade Wilson]].
* CaliforniaDoubling: The film was mostly shot in New Zealand.
* ContractualImmortality: It ''is'' a prequel, after all. For that matter, ForegoneConclusion and SavedByCanon.
* CowboyBebopAtHisComputer: A review in ''The Straits Times'' states that Logan is American, when he is really Canadian.
* CreatorBacklash:
** Creator/HughJackman 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 ''Film/TheWolverine''.
** Creator/RyanReynolds [[https://twitter.com/VancityReynolds/status/593754770113835008 is in on the "Barakapool" hate as well]].
** Director Gavin Hood [[http://www.indiewire.com/article/gavin-hood-x-men-origins-wolverine-eye-in-the-sky-20160308 has even more regrets]], given ExecutiveMeddling neutered what he and Jackman wanted and took control from his hands. [[http://www.cinemablend.com/new/Why-Deadpool-Worked-Better-Time-According-Guy-Who-Directed-Him-Last-Time-122707.html Deadpool is also in his criticisms]], particularly as the character is tailor-made for an R-rating.
** Creator/TwentiethCenturyFox seems to regret the movie too, given that it allowed the many, ''many'' potshots against it in the promos for ''Film/{{Deadpool 2016}}''.
* ExecutiveMeddling:
** The Fox executives decided that it would be a '''brilliant''' idea to take ComicBook/{{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: The version of Deadpool appearing in the film has gained a few, mostly related to how he is really nothing like the Deadpool from the comics. The most popular one appears to be DINO (SelfDemonstrating/{{Deadpool}} InNameOnly). He is also referred to as "Dudepeel" by {{Imageboards}}, "Cesspool", "[[Franchise/MortalKombat Barakapool]]" (because of the swords in the arms) and probably others.
* 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''.
* MoneyDearBoy: Creator/LievSchreiberís decision to appear in the film probably had a lot to do with the birth of his two sons.
* OldShame: Creator/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: Played straight, but eventually subverted. This movie was intended to be the first installment of an ''X-Men Origins'' film series [[{{Spinoff}} spun off]] from Fox's ''Film/XMenFilmSeries'', to be followed by ''X-Men Origins: Magneto'', ''X-Men Origins: Deadpool'', and ''X-Men Origins: Gambit''. 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. Years later, Fox would put resources into making ''Film/{{Deadpool|2016}}'' and ''Gambit'' movies, but without any actual connection to this film.
* TroubledProduction: The film was delayed by weather and Creator/HughJackman's commitments with ''Film/{{Australia}}'', begun with an unfinished screenplay due to the writers strike --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; characters such as Gambit and Deadpool were also late additions -- and saw director Gavin Hood entering conflicts with studio 20th Century Fox (along with the second unit who made action scenes too different from what he wanted), 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.
* LongRunners: 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 leads with eight given ''Film/{{Deadpool|2016}}'' is the only X-Men movie without Wolverine, followed by three actors who appear in seven Franchise/MarvelCinematicUniverse films (Creator/SamuelLJackson, Creator/RobertDowneyJr [[note]]who [[Film/XMenFirstClass like Wolverine]] owes one credit to [[Film/TheIncredibleHulk a cameo in a dingy bar]][[/note]] and Creator/ChrisEvans), and Stewart is third with six appearances [[note]]in ''Film/XMenFirstClass'' and ''Film/XMenApocalypse'', both Wolverine and Xavier are featured, but Xavier was played by Creator/JamesMcAvoy.[[/note]].
* WhatCouldHaveBeen:
** Creator/MichaelCHall was at one point considered for the role of William Stryker
** Creator/KarlUrban and Creator/GerardButler were both considered for the part of Victor Creed
** Creator/MichelleMonaghan was offered the role of Kayla Silverfox.
