"While problems in a ﬁlm are fairly easy to identify, the sources of those problems are often extraordinarily difﬁcult to assess. A mystifying plot twist or a less-than-credible change of heart in our main character is often caused by subtle, underlying issues elsewhere in the story. Think of it as a patient complaining of knee pain that stems from his fallen arches. If you operated on the knee, it wouldn't just fail to alleviate the pain, it could easily compound it. To alleviate the pain, you have to identify and deal with the root of the problem. The Braintrust's notes, then, are intended to bring the true causes of problems to the surface--not to demand a speciﬁc remedy. We don't want the Braintrust to solve a director's problem because we believe that, in all likelihood, our solution won't be as good as the one the director and his or her creative team comes up with."Here is an excerpt from Ed Catmull's soon to be published book Creativity, Inc.
