G.I. Joe: Retaliation is a 2013 American military science fiction action film based on the G.I. Joe toy line. It is the second installment in the G.I. Joe film series and the sequel to G.I. Joe: The Rise of Cobra (2009). Directed by Jon M. Chu and written by the writing team of Rhett Reese and Paul Wernick, the film features an ensemble cast with Lee Byung-hun, Ray Park, Jonathan Pryce, Channing Tatum, and Arnold Vosloo reprising their roles from the previous film, while Luke Bracey and Robert Baker take over the role of Cobra Commander, replacing Joseph Gordon-Levitt, and D. J. Cotrona, Adrianne Palicki, Ray Stevenson, Bruce Willis, and Dwayne Johnson round out the principal cast. In the film, heavy machine gunner Roadblock (Johnson), along with the surviving G.I. Joes, exacts vengeance on Cobra for his intelligence and infantry specialist Duke (Tatum) and their comrades' deaths, after a Pakistan incident involving nuclear warheads in which the Joes become traitors.

Originally slated for release in June 2012, the film was delayed in order to convert to 3D and boost interest in international markets. G.I. Joe: Retaliation was released in the United States on March 28, 2013, by Paramount Pictures. The film received generally mixed reviews from critics, although it was considered an improvement from its predecessor and grossed $375.7 million worldwide against a budget of $130–155 million.
