Jim Caviezel was in a golf movie-- Bobby Jones, Stroke of Genius. Gibson isn't interested in acting these days, much, I don't think. He likes making movies more. He also has a TV production company, too. He's very busy. He's also got the Maccabees movie to work on.
Yes, but as I said above, that was already shot and awaiting release when "The Passion" came out. He has nothing in the pipeline.
