Sorry to revive an old thread, but just last month I completed my own upscales of both Ewok films (under the pseudonym “Project Ewok”) and both are available on the SWT forums. I see they’re starting to spread around other sites now as well.
Rancor022’s Project Ewok | Caravan of Courage & The Battle for Endor - 4K Upscales (Released)
^ that sounds like a couple of quality projects for the two under-rated Ewok theatrical films - nice one 😃
