Yes, not bad for US$20,000, was it?
US$20,000 is about what Lucas is probably spending per second of screen time for Episode 3. Let's do some rough math:
US$20,000 x 60 seconds x 120 minutes = US$144m
Yes, sounds about right. Just think about that. US$20,000 per second. Even more than what the U.S. government spends!
