Will Arnett took to Conan last night to promote Up All Night, but the conversation mostly resided elsewhere as the comic actor talked about voicing Batman in the upcoming animated Lego movie entitled Lego: The Piece of Resistance. He also discussed returning to Arrested Development and his online marketing company DumbDumb which he runs with Jason Bateman.
Up All Night airs Thursdays on NBC; Lego: The Piece of Resistance arrives in theaters on February 7, 2014; and Arrested Development season four debuts on Netflix next spring.
