If you loved every colorful, uplifting moment of The Lego Movie [1], you need to see the trailer for the spinoff, The Lego Batman Movie. Will Arnett [2]'s saucy caped crusader is back in action, and this time, the main cast includes Batgirl (Rosario Dawson [3]), Alfred (Ralph Fiennes [4]), Robin (Michael Cera [5]), The Joker (Zach Galifianakis [6]), and Mariah Carey [7] as the mayor. Yes, that Mariah Carey. The movie is out Feb. 10 next year, and you can watch the new trailer from Comic-Con above and the first teaser below.
