The film stars Vincent Price, Charles Bronson and Henry Hull and was directed by William Witney and produced by Samuel Z. Arkoff, Anthony Carras (who also edited) and James H. Nicholson.

A man known only as Robur shoots down and takes on board his flying ship Prudent, his daughter Dorothy, her fiancé Evans, all of whom were exploring a volcanic crater in their balloon, along with US government agent Strock, who had hired them to look for evidence of an eruption.

The supposed eruption was caused by Robur working on his airship; he had also inadvertently broadcast a biblical passage over a voice amplifier, stirring religious fears among the citizenry of the nearby town.

[4] Robur, genius, inventor and, in this instance, creator of the powered heavier-than-air craft Albatross, with his hand-picked crew, chooses to use weapons of war to force the governments of the world to lay down their arms and live in peace.

The 2021 Kino Lorber Blu-ray release of the film includes an audio commentary by Tom Weaver, Lucy Chase Williams, David Schecter and Richard Heft.

The movie served as an influence on Star Trek creator Gene Roddenberry who conceived of a television show featuring an airship in the late 1800s with a multi-ethnic crew that went around the globe fighting injustice and righting wrongs.
