Let's look in on one of the wildest science-fantasy heroes of all...
...and, yes I said "science-fantasy", since scientific accuracy (even for the 1940s) isn't one of the story's priorities, so it ain't "science fiction", per se!
But it is a helluva lot of fun, and that's what counts!Basil Wolverton.
The sheer unfettered imagination of the man was astounding, creating vistas and aliens far beyond anything the technology of moviemaking at the time (except for animation) could match.
With the current fascination for high adventure and fantasy, SpaceHawk would be an ideal project for either theatrical or direct-to-home video, and I'm surprised no one is doing it!
