Meet Robin — and the Joker! — in the Trailer For The Lego Batman Movie

If you loved every colorful, uplifting moment of The Lego Movie, you need to see the trailer for the spinoff, The Lego Batman Movie. Will Arnett's saucy caped crusader is back in action, and this time, the main cast includes Batgirl (Rosario Dawson), Alfred (Ralph Fiennes), Robin (Michael Cera), The Joker (Zach Galifianakis), and Mariah Carey 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.
