What's that you say? You didn't know there was a secret? Well, various internet wonks have been kicking around a very intriguing theory about Grant Morrison and Frank Quitely's All Star Superman -- the Absolute Edition of which hits stores tomorrow -- involving its villain, Lex Luthor. In his latest column at Techland, Douglas Wolk sums up the All Star Superman secret theory and runs down all the available evidence for it. If you're the sort of person who enjoys picking apart literary mysteries for which there aren't obvious answers present in the text -- from Mulholland Drive to the end of The Sopranos -- this is very much the article for you. And even if you aren't, it'll give you a whole new way to look at one of the past decade's greatest superhero comics, which is always a good thing.
