The just-released Man of Steel film, which I don’t plan to see, has already generated speculation about who would play Lex Luthor in the now-likely sequel. Benedict Cumberbatch is a popular choice. He’s played a genius (Sherlock) and a superman of sorts (Star Trek Into… Really, That’s the Title?). But his most compelling credential is his voice. Put plainly: Lex Luthor is a baritone, which explains my two favorite Luthor performances.
Clancy Brown, from the Bruce Timm Superman and Justice League series.
And Anthony LaPaglia from All-Star Superman.
