When we get excited about a movie we picture something in our heads that sometimes takes years to get to. Along the way it's like looking at the plans, the scaffolding or the paintwork. It's like, "This is going to get covered in plaster... This is going to get painted..." When you get to the end you get to a moment where you get to check with your imagination if it fits and there always comes a time where you think, "I can't come up with anything new..." But then comes a moment where it's like, "Holy crap, this is more than I ever thought we'd get in the movie!" It's a fun process to watch.
