The Excorcist is the ultimate horror film.

The Shining is another horror classic, but more of a mindf**k than actually intense.

Jacobs Ladder is a deeply disturbing, phycological horror.

If you want a decent modern slasher (as there rarely is any today), try High Tension. Extremely gory and very intense. I hope you have the oatience to read subtitles, though.

Audition is a japanese classic and features one of the most villainous females in film history, and one of the most infamous torture scenes.

Battle Royale, although more of a disturbing action film, is considered a horror for it's such horrific and disturbing plot and theme. Anoter foreign film, a class of students a put on an island and must kill each other before the time limit until one is left standing. Thats just an overview of the disturbing yet powerful film about teenage violence.
