TNT has cast Harold Perrineau and Jenn Lyon in the dramedy pilot “Claws,” from Warner Horizon Television. They join the previously announced Niecy Nash in the project, which is being executive-produced by Le Train Train’s Rashida Jones and Will McCormack, and written by co-executive producer Eliot Laurence.

Also announced, Janine Sherman Barrois is set as executive producer and showrunner of “Claws.”

Nicole Kassell will direct the pilot.

“Claws” is described as a wickedly funny, midnight-dark meditation on female badness which follows the rise of five diverse and treacherous Florida manicurists. We will soon find out there is more going on at the Nail Artisan of Manatee County salon than silk wraps and pedicures.

Perrineau has been cast in the series regular role of Dean, the mentally-ill twin brother of Nash’s Desna, the owner of the nail salon at the center of the series. He and Desna adore each other, and he relies on her for everything. They also share a crappy apartment, from which Dean dreams of the good life.

Lyon will take the series regular role of Desna’s best friend and co-worker, Jennifer. A former hard partier who is now tenuously sober, Jennifer is a married mother of two young girls who deeply loves her husband and kids, but sometimes feels trapped.

“Claws” comes to TNT from Le Train Train in association with Warner Horizon Television and TNT Original Productions.
