Nevin’s Ringworld series, Laumer’s Retief series and Lewis’s Silent Planet series.
Hollywood did a great job on those films!
Who’d think there was anyone in that town with wit and competence to bring them to the screen and make a fortune!
And for anyone who was ever a ten year old boy, here’s the greatest sci fi movie you ever saw:http://archive.org/details/phantom_empire_chapter_1
...Gene Autry, an advanced underground civilization from before Atlantis, and the Junior Thunder Riders!
You keeed! You keeed!
How about “Santa Claus Conquers the Martians?” (1964)
Ok...what am I missing...I don't remember any of these being made into movies.
Greatest Sci-Fi ever... would LOVE a series based on that.
Don’t forget Slippery Jim DeGriz also.
Star Wars V “Empire” indeed.
First Men in the Moon with “Cavorite”!
Adventures of Buckaroo Banzai!
