In 1963, French novelist (and former secret agent!) Pierre Boulle, released a smashing new Sci-Fi novel called La planète des singes (Monkey Planet in the UK).

Interested in how Boulle's sociopolitical satire became one of the iconic films of our time? You can read some of the backstory about Serling's involvement with the project, then have a look at the various drafts themselves and final shooting script. [Previously].
