Im watching Dexter and the guy who plays Mike in Breaking Bad is an fbi official. The Captain in the show, big Nordic head, looks like an SS officer.

So i got to thinking about how tv has a cop "look" and a greaseball criminal look and how HBO so clearly uses CS Coon racial typing.

So that would probably create a feedback loop; kids w that look who consume thousands of hours of media must be affected in how they see themselves.

Anyway who does the type casting? Studio technicians? Are there consulting firms?
