What I look for in a script is the plot point and whether they're strong, obviously, or not, whether the characters are rich or not, and if I can do justice to the character or not. Some movies you look at and the script is so bad that no one can do anything with the script.
I approach film no differently than I approach a role. I want to make sure the movie is right, the characters are right, I can really bring something to it as a visionary, a storyteller. It's great to point a camera, but can you tell a story?
