There won't be another PI because there won't be another Arnold. Even though there are great scenes that don't include him, the movie is basically about him. (Even though that wasn't the original intention from what I understand) As others have said, the RTB movies are supposed to be great docs on the lifestyle and rigors of bodybuilding. I really need to order copies of both one and two because the clips I've seen look so well done and it's rare to hear anything negative about the films. Also Marcus Ruhl's dvds especially the last two are awesome. He is like two sides of a coin when you compare the goofy, kind, laid back man outside of the gym to the monster he becomes inside it.
