Oh, @filmfann, you think Being John Malkovich is dark? I thought it was inventive, quirky, weird, and downright hysterical in places, but not dark. Well, okay, maybe a little dusky. But what puts it at the dark end of the scale for you, relatively speaking?
All humor requires darkness, even if only soft shadows. In my mind laughter and death are first cousins. Not that death is humorous but that humor consists of tiny tragedies.
