Will Arnett is my fourth favorite Batman of all-time, in any genre (Christian Bale, Kevin Conroy, Michael Keaton precede). His Batman in The LEGO Movie managed to completely mock the character, but stay absolutely true to his core (albeit from a fractured viewpoint). I definitely think an entire movie of this is warranted, and the trailers have left me in stitches. Joining Arnett will be Michael Cera (Robin), Rosario Dawson (Batgirl), Zach Galifanakis (The Joker), and Ralph Fiennes (Alfred). The LEGO Batman Movie is slated for a February 10, 2017, release.
