EXCLUSIVE: Five-time Emmy winner John Larroquette has signed on for a heavily recurring role (seven out of 13 episodes) on the NBC midseason drama Infamous. It is an opulent soap in which a female detective (Meagan Good) returns undercover to the wealthy and troubled Bowers family she grew up in — as the maid’s daughter — to solve the murder of notorious heiress Vivian, who was once her closest friend. Larroquette will play Sen. Dwight Haverstock, a powerful politician who has a dark history with the family. The estranged best friend of Robert Bowers (Victor Garber), Haverstock is unpredictable with extreme appetites and big secrets. Larroquette, a Tony winner for How To Succeed In Business Without Really Trying, recently wrapped Gore Vidal’s The Best Man on Broadway.
