Well I took a sabbatical. I walked away from shooting movies because I couldn't handle the travel. I'm a single parent. I had young kids and I found that keeping in touch with them from hotel rooms and airports wasn't working for me. So I stopped.
If there is a book that the script came from you have to read it you have to see what you can get out of it: mood back story and things that may not even be in the film. They kick off your imagination and broaden the character I think.
