Don, you should pick up a copy of Hero With a Thousand Faces. Great read.

Back to IT CAME FROM OUTER SPACE, though... it's funny that while the film is heralded as one of the 3-D greats from the '50s (although in many ways, it is), as there are some fatal photography flaws in it. I only recently noticed that the opening shot of the spaceship crashing is in reverse stereo (ie. the left and right eye are switched), while the titles are correct!
