What was the tentative title of the canceled Lego Batman sequel?

The tentative title of the canceled Lego Batman sequel was Lego Superfriends. The project was intended to follow The Lego Batman Movie and broaden its focus from Batman’s solo conflicts to his relationship with the Justice League.

Chris McKay confirmed in December 2018 that a sequel was in development and that he expected to direct it. In 2021, he said the screenplay was being written by Michael Waldron and Dan Harmon. The story reportedly would have explored Batman’s complicated relationship with Superman and the wider Justice League, with Lex Luthor and OMAC serving as major antagonists.

The sequel was abandoned after Warner Bros. lost its Lego film arrangement and Universal Pictures acquired a new film deal with the Lego Group. “Lego Superfriends” is therefore a development title, not a released film. It should not be confused with The Billion Brick Race, another canceled Lego project, or with Lego Batman 2: DC Super Heroes, which is the title of a 2012 video game.
