The Air and Space Museum has a couple of nice presentations they have put together about how Hollywood has approached showing what going into space will look like over the years. On the Rocket Pioneers page they have a list of early rocket scientists, pretty much the men who invented the entire concept of using rockets to get humans into space. As you read through the entries you will see references to the various science fiction movies they consulted on, such as Fritz Lang’s Frau im Mond. Be sure to check the film clips at the bottom of the page while you are there. They also have Hollywood Spacesuits, and the subtitle to the article says it all: A sci-fi historian’s guide to movie spacesuits, from wacky to realistic.
