During a conversations with IGN, Jared Leto was asked what his version of the Joker would think of Superman… “Ah, ‘Who?’ That would probably be his answer. ‘Super-who? Superboy? He sounds cute. Tights? A cape?’ Superman seems like a lot of fun though for the Joker. The Joker and Superman would be interesting to see onscreen because Superman’s so stoic and morally centered. I think that the Joker would really enjoy that. Superman is just the classic hero and the Joker opposite any hero would be really interesting.”
