I'm not asking for it to be realistic, just not blatantly contrary to some very basic scientific concepts. Super-powers are inherently unrealistic, but if I'm going to accept them as part of the rules of the universe I need something either somewhat plausible or so outside my field of knowledge that I can just accept it without questioning (magic, nanobots, etc). If that line was a joke, the director clearly didn't know it. If it was serious, someone should have called them on how implausible it sounds or provided a reason why it wasn't. Otherwise, just don't bring it up.
