On 6/24/2011 the Portland (OR) composers and musicians collective Filmusik gave this film its full treatment, screening it at the Hollywood Theater in Portland with the sound turned off, while the local progressive jazz band Blue Cranes performed a new, original musical soundtrack live, and voice actors from the Willamette Radio Workshop recreated the dialogue with live Foley. [Jim Aupperle], co-writer, associate producer and head of special visual effects for the original film, was on hand for the show and said later " . . . I don't think I ever enjoyed our film as much as I did that evening."
The dinosaur that Capt. Lee Norsythe encounters near the end of the film when he is trying to get the T-rex's attention is based on the Rhedosaurus, the fictional dinosaur from The Beast from 20,000 Fathoms (1953). Ray Harryhausen visited the studio during production and gave his consent for the creature's cameo appearance.
The fermented berry juice in the film was actually grape Kool-Aid.
The first draft of the script for the film was written in three days.
The spaceship interiors in the film were the only scenes in it that were shot on a soundstage.
