I've just had a thought after watching the trailer for the Lego Batman movie - Will Arnett should be Batman. As in the normal movie version. Hear me out! We ALL know the best Batman's happened before the Dark Knight rose his stupid, menacing head and that the campy Adan West TV version, and also the George Cloony incarnation is awesome! I really think that Will Arnett encompasses all of what Batman should be - slightly camp, slightly comedic AND slightly dark (he has the best choice ever! 😍😍😍)
