Zach Galifianakis describes why he enjoyed voicing the Joker in The LEGO Batman Movie and what made it such a great experience. Zach reveals he drew his inspiration for the character from Jack Nicholson’s famous portrayal of the villain. Zach describes the dynamic he and his fellow co-star Will Arnett, who plays the caped crusader, share, saying that they improvised the “jealousy and interpersonal relationship” of the two characters. He goes on to admit that the built-in rapport he shares with Will was helpful. For Zach, it was like a bunch of friends had gotten together, and that made the experience that much more enjoyable.
