NBC has stopped production on "Outlaws," and that -- as they say -- is that. When productions are stopped, they never come back. Therefore, an actual official "cancellation" or "on hiatus" notice is a mere formality. Variety reported this a short while ago, noting that at least two more episodes were in the can.
Yes, this is too bad: You never want to see people thrown out of work, but the pilot had so many serious problems that you have to wonder why -- or how -- NBC missed them in the first place.
