Hello everyone, i'm looking for a movie that I watched years ago.
I think that movie is happening in some mental hospital. Well some doctor (main character - I don't remember his name) goes crazy through the movie, as I remember he sees some man that is probably devil or Satan but in form of the man. I remember that at the end of the movie everything goes gray and he sees all the people that he known. I think that at the end of the movie he sees hell...
I also remember that this ''doctor'' near the end of the movie sees a woman bringing flowers (or something like that) for which he later finds out he is actually that man (that is devil or satan).

I think that main character is black and the person that plays the human form of the devil is caucasian.

I know that description really sucks but you should get the idea.
