If you don't mind subtitles:
Headhunters
Oldboy
I saw the devil
The Chaser
I'd co-sign all these, though American Psycho might be out of place given his specification that he's looking for something realistic.
If subtitles are okay, definitely seek out Tell No One (it's on Netflix instant). If you like it, try Red Lights and Lemming (also French).
If you haven't caught the 70s classics, a lot of them hold up really well, and lean far more towards realism than explosions. Marathon Man, Three Days of the Condor, Duel, Charley Varrick, Deliverance, Assault on Precinct 13, etc. Must see films, all.
