Christmas is supposed to be a happy, festive time of year as you gather with loved ones, open presents and sip eggnog. Which is why when, say, terrorists, vicious outlaws, or evil gremlins crash your party, it's one heck of a buzz kill.
You're invited to relive some of cinema's most nightmarish Christmas scenes -- and we're not talking about the ones where you run out of Scotch tape or punch. We're talking severed heads, your house being blown to smithereens, and other not-so-jolly holiday happenings. Cheers!
