In an exclusive scoop from The Hollywood Reporter it is being reported that Michael Cera will be providing the voice of Robin in the upcoming The Lego Movie spinoff film Lego Batman for Warner Bros
The Lego Movie introduced its version of Batman and actor and comedian Will Arnett voiced him. Arnett will be returning to play the role yet again for this new spinoff. Batman was a stand out character in the previous film so it seems natural that the studio would decide to continue using the character.
The addition of Michael Cera as Robin will add a new layer to the series that should bring some of the same comedy from the first film.
The Lego Movie‘s animation supervisor, Chris McKay will direct Lego Batman with Dan Lin, Roy Lee, Phil Lord and Christopher Miller taking on the producing role for this project. The film will also be written Seth Grahame-Smith.
It is set to be released sometime in 2017
