thenewgreen, unfortunately, I don't think I can suggest any as there don't seem to be many at all. At least not on my out dated movie radar. I do think there are some movies that touch upon aspects of the process of transhumanism that are worth watching, for not only the transhumanist aspects but also because they are just incredibly constructed stories. 2001: A Space Odyssey tops my list. Have you watched it yet? And if reading is something you are willing to do, or audio book listening, I also would suggest reading anything by Isaac Asimov. Again, not officially transhumanist stuff, but still very interesting. Also, I find hidden gems in old radio episodes of the X-Minus One series. Again...not specifically transhumanist topics, but a really great sci-fi series to experience.
Thanks for the suggestions, I've never heard of the X-Minus One series.2001: A Space Odyssey tops my list. Have you watched it yet?
-Absolutely, a wonderful film. I was just racing this Brainpickings post about Kubrick that you may find interesting. As for Asimov, the only bit of his I've read is The Last Question, which user92 posted a while back. I really enjoyed it.
