this is a great thread. i do visual effects for film and tv, and i have to tell you, making a movie is chaos, and there aren't really any experts on anything around, or people doing any kind of intensive research unless it's in the budget. and it's almost never in the budget. as far as doing it in post, with computers, that's my bit. when they show you the 30 second bit on how they did all those great shots in your favorite movie? that 30 second bit took a team of sun deprived, really bitterly sarcastic people a couple of weeks to make.......
