He’s Batman, Lego Batman.

The toy brick version of the superhero (voiced by Will Arnett) steps into the leading man role in The Lego Batman Movie (due out February 10, 2017) after spinning off from 2014’s The Lego Movie.

While the world readies for Ben Affleck to appear as the human caped crusader in Batman v. Superman this weekend, Arnett’s Lego Batman will show off a first trailer on Wednesday — featuring a full-Lego view into billionaire Bruce Wayne’s secret lair.

“The Batcave is even better than we remembered it, it’s awesome” says Arnett. “But I also love getting into the ho-hum day-to-day of being Batman and what it’s like to fight crime each day. Like the idea of Batman oversleeping his alarm clock makes me laugh. It really does humanize him.”

Director Chris McKay, the animation director for The Lego Movie, says it was clear immediately how popular Batman was in his past supporting role, especially with fan-repeated lines like “I always work in black, and sometimes very, very dark grey.”

“We thought if we can tell a well-rounded, funny story that’s action-packed, we can build a big movie around this character,” says McKay. “This is the movie we would want to see.”

The story is set around the solitary figure in his killer hide-out — all the Batsuits and silk kimonos he wants — but whose main relationship is with his butler Alfred (voiced by Ralph Fiennes). Batman’s world upends with the introduction of Dick Grayson (or Robin, voiced by Michael Cera) and Barbara Gordon (or Batgirl, voiced by Rosario Dawson).

“Batman is an island onto himself, the only thing he doesn’t have is relationships,” says McKay. “We're making About a Boy as directed by (action director) Michael Mann.”

Besides Batman’s nemesis The Joker (voiced by Zach Galifianakis), McKay’s team has included female roles in the traditionally “guy-centric” Bat-story. Mariah Carey voices Gotham's mayor, for example. Batman will also be joined by a league of superhero friends.

“We’re nothing but exhaustive about the cameos and other characters that try to enter Batman’s life,” says McKay.

McKay is deep in production in Australia completing the intricate 3-D and fully-Lego world as created by computer animation programs which follow the principles of existing Lego bricks.

“At first it doesn’t look like it’s all built in Lego. But as you get closer you realize it is,” says McKay. “We’re building an entire city, the Batcave and vehicles, going deep into Batman’s world.”

Arnett’s deep, yet comedic voice comes ready made. He goes low with hints of clueless.

“We get down to that perfect sweet spot for Batman, but also having moments of hesitation,” says Arnett. “There’s nothing better than a guy who has this super-authoritative, brooding, voice but also moments where he’s a bit unsure.”

One thing Arnett is sure of, he will definitely be pro-Affleck over Henry Cavill's Superman watching the Batman vs. Superman movie.

“I’m going to just to enjoy the show, but I’ll be rooting for Ben," says Arnett. "I mean, he's Batman."
