Probably a lot of interview stuff, documentary style....talking about the documented past between the two, culminating with their 3-round sparring. That's how I'd set it up at least. They got a cool story w/ Dana being a former boxercise instructor, and used to manage Tito Ortiz. Used to get the better of him in sparring until Tito got bigger and better. The whole back-story between those 2, including all the political shit involved with Ortiz/UFC dealings, would make a good story leading up to a sparring match.
