Lex Luthor. Hes not any of the Lexes that youve seen, thats for sure, says Snyder, other than him being a captain of industry and one person to the world and another person to himself. And bald, of course. Eisenberg might not be the first person youd think of to play the supervillain, but he did have experience portraying a morally challenged billionaire in The Social Network. And this edition of the follicularly challenged megalomaniac taps into a similar hyperintelligence mixed with malignant straight shooting. Our Lex is disarming and hes not fake, says Snyder. He says what he believes and he says whats on his mind. If you can unravel the string and decipher what he means, its all there.
