I enjoyed:

High Tension
The Descent (1 & 2)

The other movies mentioned, I would like to check them out some time.

High Lane is another of my faves.

I am from Ireland, so they are pretty much all Foreign Films to me :-)

North or South? ::big grin::

I was going too say this one too but I couldn't remember if it was foreign or not.....::embarrassment::

Awesome!! I am Irish, McCord bloodline. I hope to get there some day so I can see where my roots started ::cool::

-Juan De Los Muertos
-Lobos De Arga
-Mientras Duermes
-La Horde

can't believe no-one has mentioned two of the best horrors ever

dead snow and troll hunter, also well worth a mention, though i can't remeber the name of it right now, is that modern slasher one set in a deserted hotel,it's norwegian or swedish or some country where it snow a lot anyway

Dead Snow was mentioned earlier up the post.

let the Right One In

The Orphanage

3 Extremes
