I would be very surprised if this would feature new live footage. I guess that this new version sound more of a Mercury "cash in" (no pun intended this is their job) with minimal to no involvement from Mark. So they take the existing cut, apply some cleaning if needed (this is shot in video format not 35 mm if I remember well), even crop the image to widescreen format, mix the sound for 5.1 and that's it.
