And it’s absolutely delightful. We get some warm-up by LEGO Batman (voiced by Will Arnett) and get to see the titular hero interact with the Batcave.
The teaser description gives us some further plot hints:
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.
The film is directed, soundmixed, choreographed, and painstakingly beatboxed by LEGO Batman (aka, directed by Chris McKay, produced by Dan Lin, Roy Lee, Phil Lord and Christopher Miller, and starring Will Arnett, Zach Galifianakis, Michael Cera, Rosario Dawson and Ralph Fiennes), and comes out February 10, 2017.
