Along with Wonder Woman and Justice League, Warner Bros. has released a new trailer for The LEGO Batman Movie.

While it’s not quite the sequel to The LEGO Movie, it is a spin off and features Will Arnett as Batman himself and Michael Cera as Robin. We finally get to learn why Robin never wore pants.

Joining Arnett and Cera in the film are: Rosario Dawson as Batgirl/Barbara Gordon, Zach Galifianakis as The Joker, Ralph Fiennes as Alfred Pennyworth and Mariah Carey as the Mayor of Gotham.

The LEGO Batman Movie is set to land in theaters February 10, 2017.

Film synopsis:
In the irreverent spirit of fun that made “The LEGO® Movie” a worldwide phenomenon, the self-described leading man of that ensemble – LEGO Batman – stars in his own big-screen adventure. But there are big changes brewing in Gotham, and if he wants to save the city from The Joker’s hostile takeover, Batman may have to drop the lone vigilante thing, try to work with others and maybe, just maybe, learn to lighten up.
