Guardians of the Galaxy Vol. 2 is a 2017 American superhero film based on the Marvel Comics superhero team Guardians of the Galaxy, produced by Marvel Studios and distributed by Walt Disney Studios Motion Pictures. It is the sequel to 2014's Guardians of the Galaxy and the fifteenth film in the Marvel Cinematic Universe (MCU). Written and directed by James Gunn, the film stars an ensemble cast featuring Chris Pratt, Zoe Saldana, Dave Bautista, Vin Diesel, Bradley Cooper, Michael Rooker, Karen Gillan, Pom Klementieff, Elizabeth Debicki, Chris Sullivan, Sean Gunn, Sylvester Stallone, and Kurt Russell. In Guardians of the Galaxy Vol. 2, the Guardians travel throughout the cosmos as they help Peter Quill learn more about his mysterious parentage.
The film was officially announced at the 2014 San Diego Comic-Con International before the theatrical release of the first film, along with Gunn's return from the first film, with the title of the sequel revealed a year later in June 2015. Principal photography began in February 2016 at Pinewood Atlanta Studios in Fayette County, Georgia, with many crew changes from the first film due to other commitments. Filming concluded in June 2016. Gunn chose to set the sequel shortly after the first film to explore the characters' new roles as the Guardians, and to follow the storyline of Quill's father established throughout that previous film. Russell was confirmed as Quill's father in July 2016, portraying Ego, a departure from Quill's comic father.
Guardians of the Galaxy Vol. 2 premiered in Tokyo on April 10, 2017 and was released in the United States on May 5, in 3D and IMAX 3D. It grossed more than $863 million worldwide, making it the eighth highest-grossing film of 2017, while also outgrossing its predecessor. The film received praise for its visuals, soundtrack, and cast, though some critics deemed it not as "fresh" as the original. It also received a nomination for Best Visual Effects at the 90th Academy Awards. A sequel, Guardians of the Galaxy Vol. 3, was initially being developed for a 2020 release, but has been put on hold after the firing of director James Gunn.
