It's a version of the cgi scarlet pilot, different in approach
to the official Carlton version.
The CGI version that Carlton made (via it's in house owned Moving
Picture Company) is almost exactly like the original series- same
suit designs, same faces, just updated a little to reflect todays
audience expectations, and a hell of a lot scarier than the original.
This version was made specifically as a motion capture exercise, but possibly also the company wanted to do a sexy looking version of the show to impress Carlton. So they very quickly knocked up this promo. This explains why the voices and faces are not the originals as there was no time to go to that sort of trouble.
The video clip is an MPEG file which can be played using Windows Media Player or Real player. The file has been zipped to make the download faster.
