get a digital camcorder some props and some mates, film a live intro, edit it an any video editor, use load animation and play animation to play back the video at the start of your game, not many games have live footage nowdays, the best I can recall was the sequences in Wing Commander Prophecy, they used proper actors and sets for those, and Lucasarts Jedi Knight, or you could render a sequence in some animation package, or even inside the game engine it`s self.
