Making a film is so hard. Sometimes you wish it had been impossible.
The cinema has always done hostility better than history. Perhaps that is a characteristic it shares with most of us. So, 33 years ago, the spaceship Nostromo was a beaten-up heap ready to be retired, but the engine of its story and the stealthy uncovering of its ultimate confrontation of raw hostility and Sigourney Weaver in her underwear might have been handled by a trio of Einstein, Heisenberg, and Ben Hecht (the latter a pro screenwriter, the first two theorists on larger matters of story).
