non-ghost means not supernatural stuff. otherwise everything goes. for example alien is a scary non-ghost movie.

anything that immediately comes to mind?

Requiem for a Dream maybe, those damn refridgerators are things of terror.

Showgirls
Robocop 3
Superman 4
From Justin to Kelly
Glitter
Gigli
Little Man

Nothing really scares me now but when I was a kid Helter Skelter scarred the hell out of me.

Mulholland Drive is the scariest movie that isn't a horror movie.

Silence of the Lambs comes to mind.

I know a lot of people who say Charlie and the Chocolate Factory.

I say The Wizard of Oz.

The Descent - one of the scariest flicks I've seen in a long time.

Halloween
The Exorcist

I almost passed out during that little walk down the back alley.

Requiem for a Dream
The Descent
Event Horizon
Blair Witch Project
One Hour Photo (more disturbing)

I second you there, that movie freaked me out.

Cool, I get to be the first to mention Jaws.

madonna show and tell
an inconvenient truth

When i was a kid:

War of the Gargantuas

not the movie overall, but Signs had some parts that made me jump.

Well, if Alien counts, I guess I'd say John Carpenter's The Thing.

War of the Worlds (new version)

same here.

Pee Wee's Big Adventure.

Large Marge?

You forgot the Spice Girls movie.

Midnight Express, for me.

co-sign on this. when i saw it in the theatres my heart was racing. very few movies have done that to me.

Jaws or Frailty

just from the trailers i'll throw my hat into the ring and say that the new "Rocky Balboa" monster is one of the scariest non-cg creatures i have seen in a very long time.
