How do you plan to deal with the aspect ratios? I don’t think there’s ever been a widescreen release of the Ewok movies.
That’s one reason I think it would be best to do a grindhouse version, I can use 4:3 ratio, and make it look like a bad bootleg vhs. So I guess it wouldn’t be as much of a “grindhouse”, as a foreign exploitation straight to vhs import from the late 70’s.
