Part of the charm of The Man Who Fell to Earth, written by Walter Tevis, is the time in which it was written. Like many genre novels, and sci-fi in particular, during the 50s, 60s, 70s and 80s; it was written during a period of scientific revelation and excitement. Hints existed of potential future technologies, so while writers of this time had a head-start in formulating ideas for stories set in the future, it was a period of great experimentation and creativity. Like watching the original Star Trek, there is so much enjoyment to be had in reveling in the ideas that these writers had; squeezing far-flung technological inventions that defy reality, from existing ‘analogue’ machinery (someone please point me to early, realistic descriptions of what we would call digital), such as Thomas Jerome Newton’s World Enterprises photographic film (a self-developing roll of film).
