Five Weeks in a Balloon (film) intended to exploit the hype of Fox’s own "Cleopatra" (1963). Allen's film is played much more for comedy than Juran's film. In Verne's novel and the Woolner Brothers' film, the balloon was named the "Victoria". Allen's film renames it the "Jupiter" with Allen giving the name "Jupiter II" to the spaceship on "Lost in Space". Filming took place in early 1962. It was the only film being made on the Fox lot at the time, due to costs incurred by "Cleopatra" (1963). The film was entirely shot in Hollywood except for some second unit shots in Africa. Allen wanted to
Jupiter (spacecraft) on the upper stage of the rocket. After the "Jupiter" and Exoliner move away, the rocket stage will guide the used cargo pod down for a destructive reentry. Fuel within the new cargo unit will transfer to the "Jupiter" spacecraft by unannounced means to keep the tug fueled. The refueled spacecraft will then tug the new cargo unit to the space station. "Jupiter" is planned to last indefinitely in orbit. Lockheed Martin's goal is to launch a single "Jupiter", which will be reused for each on-orbit delivery, and the ostensibly less expensive cargo units would be expended through atmospheric reentry.
