Joss Whedon and Fox TV part company due to lack of ideas.

As reported in Variety, Twentieth Century Fox have agreed to release Whedon, and in effect Mutant Enemy, from his contract, which allowed them first-refusal on any TV projects.

The reason Joss wanted out of the deal is simply because he has run out of ideas.

"I spent a lot of time trying to think what my next series would be," Whedon said. "I couldn't think of anything. When that happens, it generally means something is just not working. I didn't feel like I could come up with anything that the networks would want."

Joss had just over a year left of his contract. The new deal prevents him from developing any projects with another TV network in that time, and afterwards Fox get first refusal on any new projects he may come up with.
