Michael Cera to Voice Robin in THE LEGO BATMAN MOVIE

The Lego Batman Movie is going to be an Arrested Development reunion. With Will Arnett already returning to voice Batman, Warner Bros. is adding his former TV costar Michael Cera as Robin. The Hollywood Reporter broke the news on Thursday.

Warner Bros. hasn't announced if any other The Lego Movie actors are coming back for The Lego Batman Movie. If the studio, director Chris McKay and screenwriter Seth Grahame-Smith plan on assembling their own Justice League in brick form, there's a chance Channing Tatum and Jonah Hill could reprise their roles of Superman and Green Lantern.

The Lego Batman Movie opens on Feb. 10, 2017.
