Well, good news is a good portion (if not all) of production with him in F&F 7 is done. Not sure how much they needed a double for... just like The Dark Knight. He was in a spot just like Heath ledger getting more publicity for good quality stuff recently and his life was taken many years ahead of time.
From what I read they were only half way through production and were just on Thanksgiving break of filming. This is what James Wan was summoned quickly to Universal corporate office to discuss how to recover save the movie.
At first I didn't care much about his death but the more I learn about Paul the more I realize he wasn't like other celebs. He was a very giving guy and thought of others a lot. I guess he was in the Philippines not too long ago volunteering to help with recovery efforts.
