Here are mine, presented in no particular order:
<li><b>1. Tina gets knifed by Freddy</b>
The invisible Freddy, the body spasmodically butchered against the ceiling... I simply love this moment. It impressed me so much when I first saw A Nightmare On Elm Street as a kid, I to this day remain in trance when I watch it.
<li><b>2. Captain Howdy</b>
The Exorcist never fails to impress me, even after all those viewings. While some moments have lost their power overtime, the notorious spider walk being one of those, the allegedly 'subliminal' appearances of Captain Howdy's demonic face never ceases to install genuine fear into me.
<li><b>3. Donald Sutherland's final scene in Invasion Of The Body Snatchers</b>
Truly one of the most frightening scenes I've ever stored in my memory, this unexpected ending of Philip Kaufman's powerful remake to Don Siegel's classic remains to this day unmatched as a scary twist in a horror film.
<li><b>4. Kayako, the onryo, crawls down the stairs</b>
I'm a huge fan of the so-called J-horror and much to my own embarrassment also of many of its (usually inferior) Hollywood remakes. Sadako Yamamura's exit from the television in Ringu is spooky and effective, but Kayako's infamous decent from the stairs in the cursed house of Ju-On: The Grudge beats everything.
<li><b>5. The marines enter the abandoned compound on LV426</b>
I love Alien, an overall superior film to Aliens, however I enjoy the latter slightly more in a geeky sense. It also presents a curiously effective moment of pure terror for me, despite this particular moment's lack of explicit horror. You see, when a certain space one constantly expects to be crowded by people suddenly appears empty and silent, it oozes death like even a coffin can't. I myself arrive at school as literally the very first person, besides the janitor, every morning. During the Winter season, I do so when it's still dark outside (and inside the building). Gazing into those endlessly deep corridors and hallways, where during the day many kids produce loud noises while now there's nothing but dead air and darkness, the same scary feeling from Aliens creeps into me.
<li><b>6. Opening to Romero's Dawn Of The Dead</b>
We have yet to see our first zombie and already the very first scenes make me so uncomfortable, I'm in true horror mode. As the eerie score vibrates through the scenery, while ordinary people (like us) run around confused and try to figure out what to do next, we begin to realise that a global apocalypse is in full progression and the only chance for survival we have is to abandon everything and run away, a thought which, in a materialistic world, may feel even scarier than instant death.
<li><b>7. Bela Lugosi's piercing eyes in Dracula</b>
Granted, this is a different kind of 'scary'. It's not your regular wet-your-pants scariness as experienced by us, seasoned horror fans with a fair share of desensitisation from watching hundreds of horror films. In fact, Lugosi's Dracula is a great classic but it has lost most of its effectiveness through the decades. However, when watching this film, I condition myself to the mindset of audiences in the 1930's, which I am able to do with considerable ease. And while I feel the 'fear' on an intellectual level, much rather than on an emotional one, my fascination for this film is not without a certain degree of genuine unease...
<li><b>8. Liberate me ex inferis</b>
I saw Event Horizon in the theatre as a teenager and it has since become something of a guilty pleasure film for me. Thriving on many horror clichés, it nevertheless never fails to pull me back to my first viewing of this film, when the awkward voice recording took my breath away. I am well aware of the nostalgia factor playing a crucial part in my adoration for this film, but on top of that I am still, to this day, truly upset each time the little recording is played.
<li><b>9. Crawler caught on video</b>
Neil Marshall has yet to impress me a second time, as I honestly find most of his work rather poor, with the exception of The Decent that is. One of the best horror experiences I've ever had in the theatre comes with the video camera capturing the image of a crawler standing amidst a confused bunch of ladies in a dark cave. Always does it for me. I know it's coming, I'm prepared for it and then it still takes me by surprise!
<li><b>10. the "Gotcha!" scene from Exorcist III</b>
In an otherwise somewhat dull film, the scene of the killer in white clothes with garden scissors suddenly attacking the nurse during a fierce camera zoom effect, is a shockingly scary moment, unparalleled by anything else in the film.
