Were parts of the ANSA spacecraft in the second movie, “Beneath the Planet of the Apes” actually parts from another spaceship, from a different science fiction series or movie?
Yes. The “landing gear” as seen in the wreckage of the spaceship in the second movie was actually the landing struts from the “Jupiter 2”, as featured in the Irwin Allen TV series “Lost In Space”. The engine nozzle seen in the rear of the wreckage is actually from a USAF Titan missile. You will notice the landing struts, engine exhaust ‘bell’, and the two ‘saucer’ shaped landing pads for the struts (foreground and rear) The POTA TV series would also reach back to Irwin Allen’s “LIS” series for the sound effect for Virdon’s spacecraft when it returns to Earth in the first episode of the TV series. Jim Key tells me that this sound effect was lifted wholesale from the FX library of the “LIS” series and is, in fact, the sound of the main engines of the “Jupiter 2”. The seats in Taylor’s spacecraft, from the original movie, would later be used in the 1990’s science fiction TV series “Babylon 5”.
