The Woolner Brothers, ever on the cutting edge of cinema with rank imitations of popular hits, strike again with Flight of the Lost Balloon. In response to the upcoming release of Mysterious Island in 1961, the Woolners put together this cheapjack tale which, like Island, is partially set in a flying balloon. Doctor Faraday (Marshall Thompson) is an American adventurer living in Africa, who is sent to locate a scientist, missing since his plane went down in the wilderness. Since the area is inaccessible by motor flight, Faraday mans his balloon and takes off. Unfortunately, the film never does.
