ROFL, yeah, a total overreaction.
But I do bet theaters start a policy of not letting people in wearing comstumes to ANY movie.
But I also read this guy got in from an exit door that someone opened for him.
Just like that time I took my little girl to see Pokemon: The Movie, and then spent the next several days chasing down total strangers and attempting to squeeze them into tiny metal balls.
(... and you don't even wanna know what happened after that one time I watched Caligula...) ;)
