The LEGO Movie is blowing up at the box office and has recently surpassed $200 million worldwide. The sequel to the film has already been announced, and Warner Bros. has set its release for May 26th, 2017.
The studio has already hired Jared Stern (Mr. Popper’s Penguins) and Michelle Morgan to write the script. There's no word on or Chris Lord and Phil Miller will return to direct it. I assume most of the original cast will be back to reprise their roles, though. That cast includes Chris Pratt, Will Ferrell, Elizabeth Banks, Liam Neeson, Will Arnett, Nick Offerman, and Alison Brie.
Hopefully they are able to come up with a story that is just as awesome as the original.
