“The Madison” was previously in development under the title “2024.” Per 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 is not yet clear if the show will debut exclusively on Paramount+ or start off on Paramount Network like “Yellowstone.”

Fox will play Paul, described as “self-reliant bachelor who loves the outdoors.”

Fox is best known for his starring role in the ABC series “Lost,” on which he played Dr. Jack Shephard throughout the show’s six season run. He received both an Emmy and Golden Globe nomination for his time on the show. Fox is also known for his role in the popular series “Party of Five” and for films like “Speed Racer,” “Bone Tomahawk,” and “Alex Cross.” He most recently appeared in the Australian comedy series “Caught.”
