Lex Luthor. Actually, the Joker
Jesse played Lex Luthor in a way that really reminded me Heath Ledger's Joker on TDK. Something in his behavor, way of speach and this kind of mumbling...
I think he was one of the best things in bvs, just like Ledger in Nolan's movie, and it is interesting me if the similarity between them was in purpose.
