"[It's] right after NCIS -- the coveted timeslot," Weatherly told ET. "We all know this is a blessing we take very seriously. We all jumped up and down, but then we took it seriously."

Weatherly has signed on to play the title role in the new CBS drama, Bull, inspired by talk show host Phil McGraw's early days running one of the most prolific trial consulting services of all time.

ET got McGraw aka Dr. Phil to dish on Weatherly's portrayal of him.

"He is an amazing actor and he brings a real sense of humor to it," said McGraw, who serves as an executive producer on the project. "He's got a kind of smart-aleck attitude when he needs to have it and a real sincerity when he needs to have it. This is one smart guy."

While the show is inspired by McGraw, the talk show titan made clear that the series is not biographical.

"He breaks a lot of laws that I didn't break," McGraw explained. "First episode, I think he breaks about three laws before the commercial break. So, let's just be sure that this is inspired by but not biographical."
