Matthew Fox is the latest addition to the cast of the “Yellowstone” spinoff “The Madison,” Variety has confirmed.

Fox will star in the series alongside previously announced cast members Michelle Pfeiffer, Patrick J. Adams, Elle Chapman and Beau Garrett.

“The Madison” was previously in development under the title “2024.” According to the official logline, the show is “a heartfelt study of grief and human connection, following a New York City family in the Madison River valley of central Montana.” It’s not yet clear whether the show will debut exclusively on Paramount+ or launch on Paramount Network like “Yellowstone.”

Fox will play Paul, described as “an independent bachelor who loves the outdoors.”
