'Lego Batman Movie' teaser trailer takes us inside the brick Batcave

Teaser proves the plastic-brick superhero film, due in 2017, won't be as serious as its live-action predecessors.

The big superhero news of the moment may be the opening of "Batman v Superman: Dawn of Justice" in theaters, but there's much more Bat-citement on the horizon. "The Lego Batman Movie," starring the voice of Will Arnett, is due in 2017.

Warner Bros. Pictures on Thursday dropped a good-sized teaser trailer for the irreverent film, which promises to be a lot more lighthearted than the grim and heavy "Batman v Superman." The teaser even starts with Batman doing some beatboxing into a microphone.

In the past few days, we've gotten some glimpses into the superhero's Lego movie world, after Arnett tweeted a photo of a plastic-brick version of the Bat-logo along with the declaration "I AM Lego Batman" and USA Today published images of the Batcave.

Arnett, whose Batman was featured in the 2014 blockbuster "The Lego Movie," voices the character with a self-indulgent swagger that pokes fun at the gravelly voiced seriousness some of the live-action actors have applied to the role. (I'm looking at you, Christian Bale.)

The teaser trailer is focused on Batman's home below his home. The Batcave has a Siri-like voice-activated control system, closets full of Bat-clothes and a microwave in a well-stocked kitchen.

We don't learn much about the plot over the course of the two-minute trailer, but the video description alludes to the Joker's attempt at a hostile takeover of Gotham. "Batman may have to drop the lone vigilante thing, try to work with others and maybe, just maybe, learn to lighten up," it reads. Both Batman and Lego fans will find a lot to look forward to here.
