I saw the MTV/Johnny Knoxville film, "Bad Grandpa".
"Grandpa" does a silk vanish for a lady on the street, via a thumb-tip...which is then exposed by his "grandson". The boy yells something like "Hey, its behind (or on) your thumb!", and he grabs for the silk.
But the "expose" is not an "in-your-face" kind of thing. It happens very quickly, and the scene move on.
I purposely asked my lay friend what he thought was going on with the silk vanish & exposure scenes...and he said that he was confused by the whole thing, and that the silk was simply behind his thumb or something.
Moral: Us magicians will agonize over that scene during the entire movie...while laymen have already totally forgotten about it.
