Alien.

The marketing boys have been calling Alien The Director's Cut "the scariest movie of all time" and I think I just might agree. Certainly on my Top 10 list of the best movies. I learned today that in the first movie they used KY Jelly (right out of the tube) for the alien slime. Probably a good story about some production assistant being sent to the drug store to buy 500 tubes of the stuff ("It's not for me, really"). Oh, by the way...Matrix Revolution just sucked.
