The producers are being tight-lipped on the character but I hear Cassel will play a new villain and will be a series regular. He will co-star alongside another high-profile new series regular for Season 3, Breaking Bad alum Aaron Paul.

Created for television by Jonathan Nolan and Lisa Joy, based on Michael Crichton’s 1973 movie, the sci-fi thriller is a dark odyssey about the dawn of artificial consciousness and the birth of a new form of life on Earth.

“We’re incredibly excited to work with Vincent Cassel,” Nolan and Joy said. “We’ve been longtime fans of his and are thrilled for him to join the Westworld team.”

Westworld, from Warner Bros. TV, J.J. Abrams’ Bad Robot and Nolan and Joy’s Kilter Films, received 21 Emmy nominations for its second season, winning three Creative Arts Emmys.

Nolan and Joy executive produce with J.J. Abrams, Athena Wickham, Richard J. Lewis, Ben Stephenson.

Cassel won the César Award for Best Actor for Mesrine Part 1: Killer Instinct and Mesrine Part 2: Public Enemy #1. His previous credits include Black Swan and Eastern Promises, and he will next be seen in Underwater, directed by William Eubanks. Cassel is repped by CAA and Agence Adéquat.
