I'd love to see how good Poser figures would look in something like this. Certainly you're not going to get Titanic quality and even there, they only used CG characters as background figures as far as I know. I'm guessing that getting the lighting to look right would be difficult, but I don't know. I'm also guessing that if the Poser figure didn't have to look "human" in comparison to the actors - like the liquid metal figure in Terminator it would be easier. I hope you pursue this and show us the results.
