Deadpool is a 2016 American superhero film based on the Marvel Comicscharacter of the same name. It is the eighth installment of the X-Men film series, and is directed by Tim Miller. Written by Rhett Reese and Paul Wernick, the film stars Ryan Reynolds, Morena Baccarin, Ed Skrein, T. J. Miller, Gina Carano, Brianna Hildebrand, and Stefan Kapičić. In Deadpool, Wade Wilson hunts the man who gave him an accelerated healing factor, but also a scarred physical appearance.

Development of a Deadpool film began in February 2004 with New Line Cinema. However, in March 2005, New Line put the film in turnaround and20th Century Fox became interested. In May 2009, after Reynolds portrayed the character in X-Men Origins: Wolverine, Fox lent the film to writers, and in April 2011, Miller was hired for his directorial debut. CGI test footage created by Miller and Reynolds was leaked in July 2014 to an enthusiastic response, leading to Fox greenlighting the film that September. Additional casting began in early 2015, and principal photography took place in Vancouver, Canada, from March to May. Visual effects were provided by multiple vendors, and ranged from the addition of blood and gore to the creation of the completely computer generated character Colossus.

Deadpool premiered in Paris on February 8, 2016, and was released on February 12, 2016, in North America in IMAX, DLP, D-Box and premium large formats. The film has broken numerous box office records and generally received positive reviews; it became the highest-grossing R-rated comic book film, while critics praised Reynolds' performance, the humor, and the action sequences, but criticized the plot as formulaic. A sequel has been greenlit.
