Shortly after the news that Ben Affleck would become Batman in the upcoming Batman Vs. Superman movie, hearing a few stories about Bryan Cranston becoming Lex Luthor in the same film seemed plausible. In fact the more you thought about the more it all really fit together. Cranston already plays a nasty villain in Breaking Bad, a bald one at that, and has a history of comedy which helps for almost any comic book villain.
Unfortunately the rumors, which has been swirling for days, are completely untrue. The rumor was a doozy as well, saying Cranston wasn't just signed on for one movie but ready to do somewhere between 6 to 10 movies something akin to what Samuel Jackson is doing for the Marvel movies. The same story went on to claim Affleck was tied to do 13 films as Batman and Matt Damon was being considered for another comic book role. Somehow the idea of Damon as Aquaman wasn't enough for some outlets to do any digging since all the sources for this news comes from a fan website.
So we dream about Cranston as a villain who isn't cooking meth and killing people on TV but rather tricking Superman into fighting Batman.
