Space Jam: A New Legacy (formerly known as Space Jam 2) is an upcoming 2021 American 3D live-action/animated crossover sports comedy film directed by Malcolm D. Lee. It will be a standalone sequel to the 1996 film Space Jam and stars NBA player LeBron James, as well as Don Cheadle and Sonequa Martin-Green. The film also features the Looney Tunes characters such as Bugs Bunny, Lola Bunny, and Daffy Duck. James also acts as a producer alongside Ryan Coogler, who co-wrote the script with Sev Ohanian.
Talks for a Space Jam sequel began after the release of the first film but eventually fell through due to Michael Jordan's refusal to return. Several possible spin-offs, focusing on other athletes, including Jeff Gordon, Tiger Woods, and Tony Hawk, were also discussed but never came to fruition. A LeBron James-led sequel was officially announced in 2014, and after several years of languishing, filming began under Terence Nance in June 2019 around Los Angeles. After a few weeks into filming, Nance left the project; Lee was hired to replace him in July 2019. Production wrapped in September 2019.
Space Jam: A New Legacy is scheduled to be released in the United States on July 16, 2021, by Warner Bros. Pictures. It will mark the first theatrically released film to feature the Looney Tunes characters since the release of Looney Tunes: Back in Action in November 2003.
