A lot of times, when I'm approaching pre-production and my job, and trying to research and work on the script and whatnot it's always different.
I'm from Mexico, and I've heard some horror stories about cast members who can't stand each other. What we have on 'Jane' is a blessing. We do table reads for every single episode one day before it starts to shoot.
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.
Production is not an easy game and I would want to be prepared with the right team, script, etc before getting into it.
Just learn the whole script before you start shooting. That makes shooting a joy. Even if they rewrite, it's easy.
It doesn't seem as if there's that much of a difference between a big production and a little production, other than you have a smaller space in which to get dressed and you have a shorter waiting time.
From a producing standpoint, I think prep is everything.
It is always exciting to receive the scripts before we start on a new series.
