What's/are the scariest movie(s) that you watched?

I used to love Clive Barker books, and can strongly recommend The Books of Blood. Sadly his later books were poor but you can't go wrong with The Great and Secret Show, Imajica, The Damnation Game and Weaveworld.

easily John Landis' finest moment. The London Underground scene especially ... run!!

 Yea,that scene was particularly disturbing.  Frankenstein "Why!?"  -  The Creature " Beautiful , Victor, Beautiful"  

The bit that tipped me over the edge was the demise of 'Jane Seymour'; that kept me awake for many a night.

I have and I haven't.

Having been into "gothic literature" going back to its start with Horace Walpole and Ann Radcliffe ... and I did a "lecture" (on it) for my Literature class at the Junior College ... I was not exactly scared by films, because a lot of the images from the books were way stronger than any film could do, or EVER did. 

For an example, there are passages in Mathew Gregory Lewis THE MONK that are absolutely horrific, but trying to put that on stage, or film, is not likely to get you a lot of fans sitting in and paying for it. Also when you read things like Lord Polidori's work (he was a doctor ... remember that) ... his stories and work is laced with blood, guts and gore and then some! And of course, at this same time, a woman stood up to the men, and wrote a great story, that is still better than any film has EVER been able to do! Mary Shelley's FRANKENSTEIN ... kinda looked at all the elements around her .. poetic and otherwise ... in their Missolonghi nights for stories and drinking fun ... when even Lord Byron made fun of it by saying that writing in the bathtub was heavenly!

However, of all the films that EVER got me stunned enough (not scared!), there are a few experiences that are hard to ignore, although they do not belong in the "gothic" or "horror" area at all ... and here goes a small list.

DON'T LOOK NOW - 1973 - Film with Donald Sutherland and Julie Christie that has a very strange and upsetting end, that is harder to stomach when you factor in all the images that show a future and a past ... sometimes almost in the same image! A great film, but very tough otherwise.

I STAND ALONE - 1998 - Film by Gaspar Noe, and a film that was shown at the Film Festival here, and over half the audience had left before it was over ... why? ... a variety of things ... the film is almost all of it inside the man's mind, and it runs riot non-stop. But the one thing that is harder to deal with is a sort of Godard bit ... a gunshot separates the parts of it, and the timing is often not expected ... it's like it is random ... and it shocks you some at times, just when you get comfy with the idea/story of the film. And its visualization is brutal to say the least, but it creates a film that is really hard to determine if it is good, or just bad. The "innovations" in the ideas as the film is shown is downright original and impossible to ignore, but the conventionality that we seem to be attached to? Gets assaulted right off the bat! ... and yeah ... that is good ... we're so Hollywoody-sized that it is pathetic, and we do not even realize the lack of attention to details that would make the film better and closer to literature than it does something stupid like a shot/crossshot (worst literary significance, because the point of view changes!) and/or a kiss (the proverbial peeper ... on various sides of the two kissers!

Far worse for me are films that are way out there ... that create images in your mind that are simply way out of town ... and downright strong ... I remember watching AGUIRRE, THE WRATH OF GOD and that last 20 minutes is amazing and the filming is done beautifully, making sure that you see the arrows coming from all sides of the boat ... and the work that Klaus Kinsky puts in during those minutes are insane and amazing ... as a theater/film addict, seeing that is total magic ... as an image, it is downright horrific, and you know the end is around the corner ... but likely because of Klaus Kinsky's improvisation, it ended up being longer and scarier ... 

There are a couple of other films, but all in all, being a person that is into "perception" and specially aware of the surroundings (it's hard for folks to scare me!), makes for films a bit of a fake image ... and the only thing left is the idea ... of it all ... for example, seeing ROMAN POLANSKI'S TESS, and specially the rape scene ... is scary, because the handheld camera is the rapist! You don't always pay attention to the literary point of view in a lot of films and the cinematography, and how it affects you ... but something like this is downright scary and all I can think of is a lion finally getting his prey and start eating from it. An image that is not comforting for us at all ... but we know that it is "life", and it is something that we often dismiss!
