Here's something about copyright law.
Popeye, as a character, is public domain all over the world except here.
That said, I just wonder how much Saban bought back of its catalog that Disney was just sitting on. I know they have the live action stuff, but it would be great if they went back and bought back the rights to all the animated programming as well. Samurai Pizza Cats is finally on DVD in 2 forms (American dub and original Japanese series), but I'd love to see Eek and The Tick in complete DVD form.
