Because George Lucas needs more money...
Star Wars TV series in the works
Ugh. You know... after the release of Episode III, I distinctly remember Lucas saying he was ready to move on to other projects. So, he went back to Indiana Jones. The guy hasn't had an original idea in nearly 30 years.
I hope it is on cable because I won't have it and he won't have the chance to ruin the whole series again for me. The Clone Wars animated series was good—because he was barely involved in it. Much like Empire was the best of the original series because he had less of a role in its production.
