I wouldn't mind Cooper as Luthor. He looks smarmy enough and Limitless was surprisingly good too. I think I'd rather see him play Lex Luthor than Eric Draven, that's for damn sure.
Agreed. He certainly wouldn't be my first
choice, but I think he could pull it off-- as basically a younger, sexier version of John Shea's Lex who isn't too fond of this Superman character stealing his spotlight.
