Well what can one say. This late 50's space monster movie has The Professor (from Gilligans Island) Mr. Drysdale (from The Beverly Hillbillies) and Mark McCain (from The Rifleman). Additionally former child star and later Addams Family Uncle Fester Jackie Coogan. While the story is slow moving and a tad on the weak side as far as Sci-Fi goes, watching some of these actors outside of their famous TV character roles makes this film enjoyable. MST3K of course got a hold of this one and adds a touch of flavor. It's still a fun if yet dry Science fiction yarn.
