"Bull" is written by Phil McGraw and Paul Attanasio and directed by Rodrigo Garcia. It is based on the true story of Dr. Phil McGraw, a famous American daytime TV host and human research expert. Dr. Phil also provides legal consulting services. In reality, he served as a legal consultant for Oprah's "mad cow disease speech". Michael Weatherly, who just left "NCIS", plays the adapted character Dr. Jason Bull. He leads a company Trial Sciences Inc. that analyzes juries to develop defense strategies. He has both stature and intelligence, which makes him very attractive to the opposite sex, but he also has a very offensive and straightforward personality. Geneva Carr plays Marissa, a psychologist, neurolinguistics expert (the science of studying the relationship between the nervous system and language) and a sex psychotherapist in the team. Freddy Rodriguez plays Benny, as the only lawyer in a jury analysis team, providing legal strategies and acting as a lawyer in a mock trial. The protagonist Bull is Benny's former brother-in-law, and Benny is also the person closest to Bull's definition of a friend. Christopher Jackson plays Chunk, the image designer of the team, who prepares the appearance of the client for the court. He is also a former All-American lineman. Jaime Lee Kirchner plays Danny, an investigator of the team and a former FBI interrogator with super memory. Annabelle Attanasio plays Cable, a hacker and a representative of the millennial generation.
