First Men in the Moon

As a team of United Nations astronauts are planning an upcoming moon mission, they are approached by an elderly man who recounts a trip he took to the moon 65 years ago (in 1899) and was attacked by "Selenites," a race of ant-like beings that dwell in caverns of crystal. Based on the story by H.G. Wells and featuring the magical special effects work of Ray Harryhausen.
