In Season 3, the unexpected death of an old friend leads Billy McBride (Thornton) to take a case in the drought-stricken Central Valley where he comes face-to-face with a new Goliath: a billionaire rancher (Quaid) and his sister (Brenneman).
Simmons is set to portray the role of George Zax, who is described as the head of a family-owned and operated pharmaceutical company.
While Dern will be playing George’s brother Frank, who is a scientific genius and the ostracized black sheep of the Zax family.
Goliath is executive produced by Lawrence Trilling (Parenthood), Geyer Kosinski (Fargo), and Jennifer Ames & Steve Turner (Boardwalk Empire).
