First Men in the Moon is an H.G. Welles cinemadaptation from director Nathan Juran. When scientists in the year 1964 are confused by evidence of a long-ago space flight, nonagenarian Arnold Bedford (Edward Judd) explains all. Back in 1899, Bedford, eccentric scientist Joseph Cavor (Lionel Jeffries) and heroine Kate Callender (Martha Hyer) took a trip to the moon in a home-made space vehicle. Once on the lunar surface, they encountered an alien civilization resembling an ant colony, complete with queen, soldiers and workers. How they returned, and the aftereffects of their journey, comprise the films final third. Peter Finch appears briefly as a messenger; he happened to be visiting the set when the actor hired to play the bailiffs assistant failed to show up. ~ Hal Erickson, All Movie Guide
