Freedom of Speech revisited

[hi_im_god]

"you can't call "fire" in a crowded theater if there is no fire"

i understand not yelling "fire!" in a crowded theater. there could be extremely stupid people who hadn't noticed there was no smoke or flames. they might overreact and endanger people so busy rolling their eyes at the overused metaphor they have the popcorn knocked out of their hands.

how does everyone feel about yelling "movie!" in a crowded fire? is that constitutionally protected free speech or over a line that could get me in trouble with the authorities? might the same really really stupid people stop trying to escape and sit down for the previews?
