Video guys, what would it require to make something like that w/ the real life women talking?

I assume just obviously behind a well lighted white background (or behind one of those bluescreens), but as far as clarity goes, what type of camera would you need to reach that level of clarity (even though it obviously can't be too high for bandwidth purposes)?

I know I can handle the technical flash aspects of it, but the having a real life person interests me and I don't know dick about video.

The shooting itself would be of no big issue. Just a good lit backdrop and filming a person doing their lines.
A quality mini-dv camera will get you good enough clarity. Speed is all in the compression.
