I have two movies that have been driving me crazy for years.
The first movie seemed to center around a family in America. I think it was either a farmhouse or trailer trash atmosphere. Anyway, I remember two scenes. One is where the old guy (father or something) got angry and started threatening someone with a gun. Then something happened and the man fell down or something. Then the lady said, "You... son of a gun. You didn't have any bullets in that gun, did you?" And he said, "No! What do you think I am? Crazy?" The other scene I remember is around the end of the movie, when one of the adult brothers shows up in a helicopter and threatens to use it to destroy the house or something, but he's clearly emotionally disturbed and having second thoughts. His brother starts to count down, and the one in the helicopter keeps interrupting the count, like "10... 29... 18..." That's all I can remember from that movie, if indeed that was all the same movie.
The second movie took place in a cold northern town. The main character used to be a doctor (a surgeon, I think), and he meets this black guy who drives a car which has its interior covered with pornographic pictures. As the end of the movie comes around, we find out that the black guy is the killer. The two meet on a train, and the black guy cuts the train engineer's femoral artery, saying, "It's too late for him, doc," or something like that. Still, the main character fixes the wound and saves the day.
Does anyone know anything about either of these movies? I've searched all over IMDB and I haven't found anything so far.
