Mark Hamill isn't be the only animated Joker on the horizon.

According to The Hollywood Reporter, The Hangover standout Zach Galifianakis is in final negotiations to voice the villain in LEGO Batman, Warner Bros.’ spinoff of The LEGO Movie.

The actor and comedian previously played a comic book artist in the HBO series Bored To Death, a feature film version of which is rumored to be stuck in development. THR reports that he just completed filming on Keeping Up with the Joneses with Batman V Superman: Dawn of Justice and Wonder Woman star Gal Gadot.
