Before Dr. Phil was TV’s #1 psychologist, he was one of the best trial consultants. His former career in the courtroom is the inspiration for Bull, a new CBS primetime drama starring former NCIS star Michael Weatherly.

Watch the video above to go behind the scenes at Bull and to hear Weatherly interview Dr. Phil about his life before TV and how it inspired Bull. Hear how it feels for Dr. Phil to see his life on TV, what his life was like as a jury consultant and what he hopes people will learn about juries and trial trial science.

Bull airs Tuesdays on CBS at 9/8c.
