I had been very impressed with the voiceover of 'Apocalypse Now,' with Martin Sheen's voice. That was a great voiceover; it really internalized the Martin Sheen character, who was essentially fairly low key and didn't say a lot during the whole movie. But he thought a lot, so I always thought that was really great.
One of the problems with science fiction, which is probably one of the reasons why I haven't done one for many, many years, is the fact that everything is used up. Every type of spacesuit is used up, every type of spacecraft is vaguely familiar, the corridors are similar, and the planets are similar.
