Verified answer

During the adaptation process for the movie "Moneyball", Paul DePodesta did not approve of the way that his character was being portrayed. As a result, he refused to allow his name or likeness to be used in the movie so the character of "Peter Brand" was created as a composite of Beane's deputies in Oakland. This character is not an accurate representation of any specific real-life person.

Brand is a fictional character added into the movie Moneyball. He is based off of Paul DePodesta, one of Beane's assistants, but DePodesta didn't have nearly as big of a role that was portrayed by Brand in the movie.
