According to a message dated Nov 2, 2002 in the alt.fan.heinlein newsgroup (news:alt.fan.heinlein), his widow says they failed to renew a copyright, and the script collaborator added material to the one-hour TV script to make a movie script without his permission or cooperation. The Heinleins were appalled by the resulting movie.
shareI guess that's what comes when one worked with Producer Lippert.
Very few have come out on the winning end when working for the theater owner/producer. But he always seemed to make a dollar.

Yes and one could say the same about Roger Corman!
In this case the film works - and works well
Can't argue with his cheap skate nature, but Corman had a great eye for the different talents required for moviemaking.
Lippert was strictly a Poverty Row person.
I wholeheartedly agree. Corman's low-budget quickies usually had bad special effects but he could get A-list performances out of his actors. Look at Lee Van Cleef and Peter Graves in It Conquered the World, Russell Johnson in Attack of the Crab Monsters or Jack Nicholson in The Terror.
About the only halfway decent actor in Lippert's films was Hayden Rorke and he never got noticed until he became Dr. Bellows on I Dream of Jeanie.
Plus, Corman benefited from having his producer brother Gene along. Gene could spot the perfect locations for films. Others used sound stages but Gene could find on-location spots that made even Jack Arnold jealous.
