So we don't make it a habit of naming and shaming other sites or blogs that might post the occasional rumor (we do ourselves after all!) however unsubstantiated...but flat out lies? A certain fansite (which we still won't name or link to, any search for Cranston/Luthor will unearth it) routinely posts...well, complete horseshit for hits. Sometimes -- as in this case -- they expand on an existing rumor, and others it's incredibly outlandish garbage, plucked from thin air -- Matt Damon being in talks for Aquaman etc. Anyway, these guys ran with "Bryan Cranston Officially Cast As Lex Luthor In Man Of Steel 2", and many sites picked it up because there were already whispers of it out there. Latino Review's El Mayimbe hinted as much on Twitter, and then the actor himself didn't even debunk it when asked about the possibility. So yes, it is entirely possible that Cranston is or will be in talks for the role, but until you read that on a trade, or we get some more info on it from a TRUSTED fan source, don't believe a word. Updates if and when they come in.
