I have been driving myself crazy looking for the name of this movie. I believe I saw it on TCM or AMC a few years ago. It is a B/W film probably made in the late fifties or early sixties and is a B movie. I can only remember that the male lead murders someone and pretends to be insane to get away with the murder. The last scene is set in a living room in what seems to be a typical suburban home and the male lead is in it but he goes crazy breaks through a window and tries to run away. It turns out that he is in a mental institution and men in white coats grab him and there were doctors observing him and that is how the movie ends. It is not much to go on but any help would be greatly appreciated.
