Fox Nation is getting a piece of "Yellowstone."
The streaming service owned and operated by Fox News announced Tuesday that Kevin Costner, star of television's most-watched drama, has signed on to narrate a four-part documentary series on the history of Yellowstone National Park in commemoration of its 150th anniversary.
Costner's Territory Films is teaming with Warm Springs Productions to make the four hourlong episodes of "Yellowstone: One-Fifty." New episodes will launch weekly this fall on Fox Nation, which has a paid monthly subscription fee of $5.99.
