Granted, I knew that the green screen stuff was done, but not exactly to this extent. The Ugly Betty scene (:30) is a prime example..I mean..what?

I never knew about this but I guess it makes sense if you want to control almost every aspect of filming and you won't get interrupted by external influences like fans, planes, etc.

I would like to watch episodes of the shows in Green Screen Mode.

At the end they expect us to be suprised that the shots of actors waking around on other planets were accomplished via green screen
