The politics of saving at all costs coupled with a good ability to use scissors and assembly, rather than to kick up a fuss, in the '60s still ensures a good response from the audience and this film is one of the best known examples American science fiction films made by using long lengths of Russian films. (The seven sailors of the space) aka Planeta Burg (which is considered appropriate to mention the cast titles) comes from Harrington cut, reassembled and sewn around some specially filmed sequences in the studio (and think for themselves be reused later) with an anonymous Basil Rathbone in the scientist. The plot itself is the carbon paper copy of the story told by the director Pavlev Klushantsev
This imaginative and highly visual film is actually a Soviet-made production titled Planeta Bur, which was purchased by Roger Corman and American International Pictures and refashioned into a more simplistic science fiction-adventure for American audiences. Former experimental filmmaker and Kenneth Anger associate Curtis Harrington (using the nom du cinema John Harrington) was pressed into directing new footage featuring Basil Rathbone and Faith Domergue, which was incorporated into the film for Hollywood name value (such as it was at the time). The end result gives enticing glimpses of Russian director Pavel Klushantsev's original vision and some impressive special effects (most notably, the air car and the crew's mechanical helpmate Robot John), which are unfortunately dampened by the newer, more awkward-looking scenes. Ever the penny-pincher, Corman recycled the Russian footage for a second, less coherent feature, 1966's Voyage to the Planet of Prehistoric Women, which featured scenes with Mamie Van Doren shot by then-novice director Peter Bogdanovich.
