The Rumour: This insane rumour suggests that there's a "logical" explanation for why Superman fires a potentially lethal optic blast at Batman in the trailer despite his famous no-kill rule: he's actually not Superman at all but rather Bizarro, the iconic supervillain who is essentially Supes' evil mirror image. How Likely Is It?: 2/10. It's absurd enough to be an entertaining theory, but it'd probably be outrageously silly if played out in reality. Plus, with so many other villains already in the mix, this would probably be too much of a muchness, and the idea of Lex engineering two villains in the same movie seems too repetitive. We'll definitely be seeking an explanation about that dangerous optic blast when the movie hits screens, but this almost certainly isn't it.
