Warner Bros is definitely in the Lego business these days. With a worldwide gross of $452.4 million since its February release, The Lego Movie proved itself to be the start of a viable franchise for the studio. So now, like everybody else, the studio wants to build a “universe” around the series. Conventional sequels are out. An approach of sequels combined with spinoff films is the new model. Just ask Marvel Studios, LucasFilm, Fox, and Sony- who are all trying, with varying degrees of success, to turn their geek properties into multi-tiered “cinematic universes.”

We all ready knew a straight-up sequel to The Lego Movie was coming. But now comes word that a spinoff, based around Lego’s Ninjago line, has been greenlit. Deadline is reporting that Ninjago will be directed by Charlie Bean, and it will serve as his directorial debut. Until now, Bean has worked in the art department for several projects over the years, and served as an executive producer for Tron: Uprising.

In a statement, announcing the film, Warners domestic distribution president Dan Fellman had this to say:

“Followingthe huge success of The Lego Movie, we are very excited to build on the Lego franchise. We know there are already Ninjago collectors who can’t wait to see their favorite characters on the big screen. This promises to be a terrifically fun and thrilling entry into our Fall 2016 slate, with broad audience appeal.”

Ninjago will be based on screenplay by Bryan Shukoff and Kevin Chesley.
