The only way North Korea has the technological sophistication to pull this off is with help from the Chinese, since no one else will even look in their direction.

When did we become a society of such cosseted, mewling ninnies? You are infinitely more likely to get hit by a bolt of lightning (or, more realistically, plowed into by a drunk driver) while exiting a movie theater than attacked by a North Korean splinter cell because you saw a middling Rogen-Franco comedy.
