Last month, during Jimmy Kimmel Live!'s post-Oscars show, a "deleted scene" from Batman v Superman: Dawn of Justice was shown, featuring Jimmy Kimmel's discarded role as a man who unmasks both Batman (Ben Affleck) and Superman (Henry Cavill). This scene also featured a special cameo from Will Arnett, who revealed that he is LEGO Batman in the new spinoff of The Lego Movie, The LEGO Batman Movie. Warner Bros. decided to give us our first look at The LEGO Batman Movie, on the eve of Batman v Superman: Dawn of Justice's release, with the first photos and a poster, and today we have the very first trailer.

The photos that debuted last week gave us our first look at Will Arnett as LEGO Batman himself, along with LEGO versions of the Batcave and his Batwing, but they didn't feature any other characters from this upcoming animated movie. The poster gave us a glimpse at LEGO Batman's Batsignal, which even includes a glimpse at the Gotham City skyline embedded in this insignia. Thankfully, the trailer gives us even more of The Dark Knight, along with our first look at other iconic characters.

Will Arnett voiced the mini-fig version of Batman in The Lego Movie, which went on to become a box office hit, taking in $257.7 million domestically and $469.1 million worldwide, from a $60 million budget. That movie's success lead to Warner Bros. announcing a number of spinoffs, with The LEGO Batman Movie arriving first next February, followed by Ninjago (September 22, 2017) and The Lego Movie Sequel (May 18, 2018). Will Arnett returns to voice Batman in this animated sequel, and this time he's joined by a new supporting cast.

The story centers on Batman's solitary life in the Batcave and the only meaningful relationship in his life, with his butler Alfred (voiced by Ralph Fiennes). The plot thickens when Batman's world is upended by the arrival of two sidekicks, Dick Greyson, a.k.a. Robin (Michael Cera) and Barbara Gordon, a.k.a. Batgirl (Rosario Dawson). The voice cast is rounded out by Zach Galifianakis as The Joker and Mariah Carey as the mayor of Gotham City. Director Chris McKay, who served as the animation director on The Lego Movie, teased yesterday that several other well-known superheroes will be featured in cameo appearances, although he wouldn't mention any characters by name.

Production is still under way in Australia, creating an intricate LEGO world for this beloved superhero. The director teased they're building an "entire city, the Batcave and vehicles," and they're going "deep into Batman's world." The LEGO Batman Movie will open in quite a competitive weekend on February 10, 2017, going up against Universal's Fifty Shades Darker and Lionsgate's John Wick: Chapter 2. The following week, on February 17, 2017, it will face even stiffer competition, with Sony's The Dark Tower, Warner Bros.' Fist Fight, Universal's The Great Wall and 20th Century Fox's The Maze Runner: The Death Cure all debuting. Take a look at the first trailer, and stay tuned for more on The LEGO Batman Movie.
