Lego Superfriends was a planned sequel to The Lego Batman Movie that would have been an installment in The Lego Movie franchise, with Chris McKay returning to direct the film and the script being written by Michael Waldron and Dan Harmon. The film was set for a release in 2022.
According to director Chris McKay, the sequel would have focused on Batman's relationship with the Justice League, particularly Superman, and the main villains would have been Lex Luthor and OMAC.

Why It Was Cancelled
- Although The Lego Batman Movie received positive reviews from critics and audiences and was successful at the box office, both The Lego Ninjago Movie and The Lego Movie 2: The Second Part were box office disappointments, causing Warner Bros. to end off their movie deal with Lego in December 2019.
- Universal Pictures acquired the film rights with Lego in April 2020, which means that all LEGO-fied WB characters, including those from DC Comics, are no longer available as part of Universal's Lego Movie franchise, leading to the sequel's cancellation.
- Lego Superfriends was permanently cancelled after Warner Bros. gave up their film rights with Lego in December 2019, with Universal acquiring the rights in April 2020 and working on future Lego films, most likely rebooting The Lego Movie franchise.
- The Lego Batman Movie remains as a stand-alone spin-off film to The Lego Movie.
- Warner Animation Group decided to make DC League of Super-Pets instead.
