You Have Not Been Exposed to Joker Gas, The Lego Batman Movie Trailer Is Just That FunnyGermain Lussier7/23/16 7:38pm7617EditPromoteDismissUndismissHideGo to permalinkThis movie may be too good to actually exist. Will Arnett’s gloriously self-absorbed Batman. Michael Cera is an amazing loony Boy Wonder. For the Penguin’s sake, Robin literally throws his tights in Batman’s face. Everything about this Lego Batman Movie trailer is, as they say, awesome.
