Deadpool is a 2016 American superhero film based on the Marvel Comics character of the same name. Distributed by 20th Century Fox, it is the eighth film in the X-Men film series. Directed by Tim Miller from a screenplay by Rhett Reese and Paul Wernick, it stars Ryan Reynolds in the title role alongside Morena Baccarin, Ed Skrein, T. J. Miller, Gina Carano, and Brianna Hildebrand. In the film, Wade Wilson hunts the man who gave him mutant abilities and a scarred physical appearance, becoming the antihero Deadpool.

Development of a Deadpool film starring Reynolds began in February 2004, before he went on to play the character in X-Men Origins: Wolverine in 2009. Reese and Wernick were hired for a spinoff in 2010. They worked with Reynolds to adapt the character more faithfully (including his fourth wall breaking) after the portrayal in Wolverine was criticized for not doing so. Miller was hired in 2011, marking his directorial debut. An enthusiastic response to leaked test footage he created with Reynolds led to a green-light from Fox in 2014. Additional casting began in early 2015, and filming took place in Vancouver, Canada, from March to May of that year. Several vendors provided visual effects for the film, ranging from the addition of blood and gore to the creation of the CG character Colossus.
