• Paul Giamatti as Charles "Chuck" Rhoades, Jr.: U.S. Attorney for the Southern District of New York who later runs for Governor of New York and is elected Attorney General of New York. Rhoades is ruthless and has a particular distaste for wealthy criminals who try to buy their way out of justice. Despite his significant power as U.S. Attorney, Rhoades struggles not to be overshadowed both by his higher-earning wife, Wendy, and by his well-connected and very rich father. He went to Yale (as did his wife and his father) and has a blind trust of which his father is a trustee. In private, he and his wife engage in BDSM role play, with Chuck as Wendy's "slave."
