I'm not the only one hoping, as we can see here. Interesting that Powers' publicist is saying 'talk to Disney' rather than 'nope, not us, sorry'.
EDIT to add:
Check comments: Powers is credited as author on something that's copyrighted, and held in conjunction with Disney.
Methinks we're looking at a new era of fantasy getting into film. And I want Last Call directed by Gilliam, with Jeff Bridges as the main character. NOW.
