Via the blog Typeset in the Future: 2001: A Space Odyssey. The opening paragraph:
2001: A Space Odyssey – Stanley Kubrick’s 1968 sci-fi masterpiece – seems an appropriate place to start a blog about typography in sci-fi. Amongst other delights, it offers a zero-gravity toilet, emergency resuscitations, exploding bolts, and product placement aplenty. It’s also the Ur Example of Eurostile Bold Extended’s regular appearance in spacecraft user interfaces.
This is a witty and very knowledgeable analysis that taught me a lot about a great movie and about typefaces.
