Any Great Psychological thrillers which is not classic?

Movie that keeps you think, keep you guess, with excitement (thriller) not just with talking and talking, and which is not a classic movie that is under the year 1990. It can be chinese / japanese / korean / English.

Any other movies to recommend like:

Triangle (2009)
Prestige
Timecrimes
Prison Break
Inside man
The bank job
Death note
Internal Affairs (Chinese)
The Italian Job

-Battle Royale
-Insomnia
-Pi
-Vertigo (it's old, but seriously just watch it, it will blow your mind)

I like these:

Equus
Delicatessen
Donnie Darko
Naked Lunch

I really like these:

Harry He's Here To Help
Dragonflies
Lemming
The Beast Must Die
Death in a French Garden
The Shout
Apt Pupil
Apartment Zero
The Consequences of Love
A History of Violence
Revanche
Animal Kingdom
Anything for Her
Night of the Sunflowers
The Double Hour

You had Timecrimes in your list so I've suggested quite a few European thrillers, they tend to be good at this sort of thing.

Black Swan
Requiem for a Dream
Pi
21 Grams

Session 9
Antichrist (2009)
Oldboy
A Tale of Two Sisters
The Machinist
Seom (aka The Isle)

Intersting movie from New Zealand.

Wound

Its kinda out there

and cant go past "the Strangers"

Dark Corners - despite the attention to be graphically appealing its more of a psychological thriller than a horror

Exam - low budget thing fairly unique

Mulholland Dr., The Silence of the Lambs, Paprika, Memento, Seven, and Black Swan are great.
You might like my list of psychological thrillers.

Se7en
Oldboy
Don't Look Now
Videodrome
Santa Sangre
Caché
Blue Velvet

Funny Games
The Machinist

I will add faux documentary Lake Mungo - a few nice twists in there
