Move over Ben Affleck, Will Arnett is taking over in "The Lego Batman Movie" -- and this Caped Crusader is so entertaining, it's even fun to watch him microwave some lobster thermidor leftovers.

"I deserve this today; today I deserve it."

Warner Bros. just dropped the first trailer for the "Lego Movie" spinoff, with an intro from Batman himself, who claims he "painstakingly beatboxed" the preview himself. Not a whole lot happens in the 2-minute "Batcave Teaser," but we do spend time with the Dark Knight and his trusty Computer, who initiates the official Batcave music: Wiz Khalifa's "Black and Yellow."

According to Entertainment Weekly, "The Lego Batman Movie" voice cast includes Michael Cera as Robin, Ralph Fiennes as Alfred, Rosario Dawson as Batgirl, Zach Galifianakis as the Joker, and Mariah Carey as the mayor of Gotham. YES, MARIAH CAREY AS THE MAYOR OF GOTHAM.

Here's the synopsis from Warner Bros:

"In the irreverent spirit of fun that made "The LEGO Movie" a worldwide phenomenon, the self-described leading man of that ensemble – LEGO Batman – stars in his own big-screen adventure. But there are big changes brewing in Gotham, and if he wants to save the city from The Joker's hostile takeover, Batman may have to drop the lone vigilante thing, try to work with others and maybe, just maybe, learn to lighten up."

The movie is scheduled for release February 10, 2017.
