Warner Bros. announced on Feb. 21 that The Lego Movie sequel is scheduled for May 26, 2017.
Jared Stern and Michelle Morgan will write the sequel, reports The Wrap. Phil Lord and Christopher Miller, who wrote and directed the original, return as producers.
The Lego Movie, which cost $60 million to produce, passed the $200 million in worldwide box office less than 2 weeks after its release.
The February blockbuster has helped Warner Bros. stand out in the animated film industry, where it faces stiff competition from Disney, Pixar, and Dreamworks.
So far, the sequel is the only big animated film slated for May. Despicable Me 3 and a new Pixar movie are June releases.
