Sometimes, with the scale of a film, it's like when I walked on the sets of "The Matrix," especially in "Reloaded," there was the city square, or in "Revolutions" with some of the machine world, you're like, "Wow, this is a big playground," which is fun to watch. But the acting experience and the collaborating and creating the world, working on the piece, they're the same joys. - Keanu Reeves
