[Yo-Yo]

I still have a script that I downloaded a few years ago, that was linked here on FR (written by a FReeper?) for a movie version of Heinlein's The Moon is a Harsh Mistress.

With today's Deep State political intrigue, if done well that might be a big hit.

Ringworld is too long for a movie - and then there are the sequels.

The Moon is a Harsh Mistress would be wonderful, but, again, awfully long. But a lot could probably cut out and leave the actual story intact.

Still, Hollyweird would probably ruin both. We need a better studio system to do stories like those justice - fewer perverts, fewer ‘creative’ types, more real SF fans.
