Reason 5: Real Roles

The fifth reason is because of how dedicated everyone was to becoming their characters. Typically with acting, day one of production you haven’t actually spent a lot of time as that character and everything’s so quick. You go from one thing to the next. So it’s really through the process of filming that you find your way into the character. We didn’t want that to happen. We wanted everything to be totally prepped by the time of starting and that was the outcome. Everybody was ready to go from day one. Everybody was completely dialed in by the time we got into production.
