Listen there are some movies that are set in stone and the writer or the director does not want to change but I've never worked on a movie including my own that didn't take advantage of a rehearsal process.
I also find it interesting that a lot of people in their 30s are not married and don't have kids. There are a lot of people in this age bracket that are out there dating and trying to find love. And I never thought that at my age I would be.
