Disturbing mean the kind of movies that stay with you for days because it was so weird or sad, and had evoked strong emotions. Couple of movies from top of my head:

Midnight Express (1978): Make one think twice about smuggling drugs from another country.


Osama (2004): Tale of a girl posing as a boy in Afghanistan to find a job and feed her family. Not a movie for light hearted.


Goofellas (1990): Somebody is about to get whacked.


Fargo ( 1996): This movie is definitely a “Cold” one.


Malcolm X ( (1992):Always standing firm, even when facing death.
