The film was directed by David Leitch and written by Rhett Reese, Paul Wernick, and Ryan Reynolds, who stars in the title role alongside Josh Brolin, Morena Baccarin, Julian Dennison, Zazie Beetz, T.J. Miller, Brianna Hildebrand, and Jack Kesy.

Cable uses his last charge, reserved for his return trip to his family, to warp back several minutes, strapping Vanessa's token in front of Wade's heart so he survives the bullet.

He uses it to save the lives of Vanessa and X-Force member Peter, as well as to kill both an alternate version of himself confronting Wolverine, and Ryan Reynolds after he finishes reading the screenplay for Green Lantern.

Wanting an additional villain for the film to support Firefist for the final fight with X-Force, the writers chose Juggernaut because he is "a force of nature [who] was probably the coolest character never to be used ... in the right way.

"[17] Additionally, Robert Maillet briefly appears as Sluggo, an inmate of the Ice Box who originally had a more prominent antagonistic role alongside Black Tom before both roles were reduced due to the number of villains in the film;[46][47] Dakoda Shepley has a cameo as fellow Ice Box inmate, Omega Red;[48] Hayley Sales and Islie Hirvonen respectively appear as Cable's wife and daughter Hope, during a flashforward;[49] and the film's version of the X-Force team also includes Terry Crews as Bedlam,[50][3] Lewis Tan as Shatterstar,[22] Bill Skarsgård as Zeitgeist,[51] Rob Delaney as Peter Wisdom,[3][14] and Brad Pitt as Vanisher.

[52] Reprising their roles as the X-Men for a brief cameo are James McAvoy as Professor X, Nicholas Hoult as Beast, Evan Peters as Quicksilver, Tye Sheridan as Cyclops, Alexandra Shipp as Storm, and Kodi Smit-McPhee as Nightcrawler.

[73] A week after Miller's departure, Fox was looking at David Leitch, Drew Goddard, Magnus Martens, and Rupert Sanders as potential replacements for the director.

[75] Reynolds, a fan of Leitch's John Wick, said the director "really understands those Deadpool sensibilities and where we need to take the franchise," and "can make a movie on an ultra tight minimal budget look like it was shot for 10–15 times what it cost.

"[85] Reese and Wernick preferred to use jokes in the film that only certain members of the audience would understand, though Reynolds would not allow some to be used if he thought not enough people would enjoy them (including a reference to golfer Davis Love III).

"[86] Other cut jokes included many "bizarre" characters interviewing to join the X-Force, such as an idea to have Chris Evans reprise his role as the Human Torch from Tim Story's Fantastic Four films.

[87] Reese and Wernick confirmed in January 2017 that Stefan Kapičić's Colossus, Brianna Hildebrand's Negasonic Teenage Warhead, and Karan Soni's Dopinder would be returning from the first film to "make at least an appearance.

Another example of these color wheels was the sequence in which Firefist is introduced, with Leitch taking advantage of the scene being set during the day to overemphasize the lighting and create a general sepia/orange tone that represented the fire abilities the character displays.

[121] In February 2018, Terry Crews was revealed to have a role in the film,[50] the character Shatterstar was confirmed to be appearing,[43] and the production returned to Vancouver for six days of reshoots under a new working title, Daisy.

The character's "iconic metal ridges" were live textured by animators for the first film, but Framestore changed this to use a combination of shape movement and distortion so they could be more precise with the geometry of the lines.

[5] The choir originally sings lyrics such as "you can't stop this motherfucker" and "holy shit balls!," which ultimately earned the score a parental advisory warning.

[141][28] The video was described by The Hollywood Reporter's Ryan Parker as "completely out of left field" and setting the tone perfectly for the film, though his colleague Graeme McMillan was less positive due to not knowing of Ross (Deadpool co-creator Fabian Nicieza thought the fact that many in the audience would not know of Ross made the video "exactly the kind of quirky pop culture choice that works perfectly for Deadpool").

"[142] Rather than pay for an expensive advertisement spot during Super Bowl LII, the film's official Twitter account was used to "live tweet" the event with in-character commentary from Deadpool.

Forbes contributor Scott Mendelson called it "pretty funny and mostly entertaining," but was disappointed in it being a "conventional" trailer compared to the more out-there videos previously released for the film.

Mendelson also noted the inclusion of T.J. Miller in the trailer following the reveal of sexual misconduct allegations against the actor in late 2017, calling it "inevitable no matter how tarnished his reputation might be these days.

[149] At the end of April, Leitch stated that alternate versions of jokes that had been cut from the film were included in the trailers, since "only one can live in the movie, so we might have snuck a couple in sort of additional materials that people can discover.

[158] At the end of September 2018, Fox announced that it would release an untitled Deadpool film in theaters on December 21 in place of Alita: Battle Angel, which was moved to February 2019.

The studio suggested that press and fans "guess away" as to what this new film would be, but it was believed to be a re-cut version of Deadpool 2 that would carry a PG-13 rating rather than being R-rated like the initial theatrical release.

[162] At the end of November, writer and artist Michael Vincent Bramley noted that he had pitched the exact framing device that was being used for this version of the film to Reynolds on Twitter in December 2017.

The Blu-ray format also includes a gag reel, deleted and extended scenes, alternate takes, featurettes on Easter eggs, the cast and characters, Leitch's directing, and the action and stunts, and more.

The website's critical consensus reads, "Though it threatens to buckle under the weight of its meta gags, Deadpool 2 is a gory, gleeful lampoon of the superhero genre buoyed by Ryan Reynolds' undeniable charm.

[175] Richard Roeper of the Chicago Sun-Times gave the film 3.5 out of 4 stars, jokingly calling it the best sequel since The Godfather Part II and saying: "Deadpool 2 is wicked, dark fun from start to finish, with some twisted and very funny special effects, cool production elements [and] terrific ensemble work.

"[188] Mike McGranaghan from The Aisle Seat gave it a score of 3.5 out of 4, explaining that "Deadpool 2 is a better superhero sequel than Superman IV: The Quest for Peace, Ghost Rider: Spirit of Vengeance, and Batman & Robin.

Scott of The New York Times was critical of the cynical tone of the film, writing "something ever so slightly dishonest about this character, something false about the boundaries drawn around his sadism and his rage.

"[192] New York writer David Edelstein wrote that the film was tedious and predictable, noting "A superhero movie with the looseness of a Mad magazine parody remains a viable idea, as demonstrated by the underrated Mystery Men and, of course, Deadpool.

[228] Karan Soni, Leslie Uggams, Morena Baccarin, Stefan Kapičić, Rob Delaney, Brianna Hildebrand and Shioli Kutsuna reprise their respective roles as Dopinder, Blind Al, Vanessa, the voice of Colossus, Peter, Negasonic Teenage Warhead, and Yukio from the previous Deadpool films.
