File this one under "wild-but-fun speculation". Brandon Routh, a perennial contender in the 'nicest man in Hollywood' competition (politely tussling with Paul Rudd, Hugh Jackman and The Cloonster for the top spot, in our eyes), would love to be Nolan's Superman, and we have video evidence to prove it.
Also, did you know he was a massive World Of Warcraft addict? We did, so we asked if he'd be interested in the proposed Warcraft movie. And it turns out he's at least talking to the right people. Wow. Or rather, WoW.
