Cronenberg can still mess your head
 

I love that seen in Scanners too. Heres a couple more:

1 Ed norton looking up from a prison cell at the end of Primal Fear

2 In Cache, an immigrant slashes his own throat(that really creeped me out)

3 Inside - When La Femme is standing outside looking in smoking. She bangs her fist so hard against the window it cracks. The first time I saw the flik when this happened I thought this should be interesting. I had knowing fucking clue how right I was.

The nazi soldier creatures in the dream scene from American Werewolf in London. When I first saw that film (a too young 7 or 8) that was the scene that scared me the most.

Pure awesomeness. :cool:
