It's a bird, it's a plane, it's ... oh, it's just Clark Kent. Not Superman. Not with those glasses! It does seem like a stretch to believe that just putting on a pair of specs would be enough to disguise Superman from his alter ego. It's obviously the same dude. However, "Batman v Superman: Dawn of Justice" star did a little experiment in Times Square in New York, to show that Superman's disguise works just fine on us oblivious humans.

He doesn't even need glasses. Heck, he can even wear a Superman shirt in broad daylight on the streets, below a "BvS" poster and NO ONE WILL CARE. That's New York for you. Try to take someone's cab, maybe then they'll notice you, but otherwise they're just going to keep walking.

Cavill posted a mini video on Instagram to illustrate his illusion point, adding this polite caption:

"Dear Doubter,
The glasses are good enough.

They missed a chance to tug on Superman's cape, or at least his coat.

Apparently there's been debate over the years about why no one pieces together Clark and Supe. Here's a piece of comic history on the subject:

"The most common offered is simply that, despite their physical resemblance, Superman and Clark are perceived as too different in mannerisms and personality to be the same individual. In the 1970s, one suggestion was that the lenses of Clark Kent's glasses (made of Kryptonian materials) constantly amplified a low-level super-hypnosis power, thereby creating the illusion of others viewing Clark Kent as a weak and frailer being; however, this reason was abandoned almost as quickly as it was introduced, since it had various flaws (such as stories where Batman would disguise himself as Clark Kent, among others)."

There's more, if you want to dig into theories.

Just consider doing a quick sweep of the theater when you go see "Batman v Superman" next week. If there's a low-key guy with glasses sitting near you, he might be important.
