Costner will not be participating in the second half of season five, which is currently being shot in Montana.
He made the announcement Thursday in a video posted to social media.
“I loved it, and I know you loved it, and I just wanted to let you know that I won’t be returning,” Costner said in the video, in part. “I love the relationship we’ve been able to develop, and I’ll see you at the movies.”
Costner said he will focus on other movies including “Horizon,” the four-part Western movie series he has produced, co-written, directed, and will star in.
The actor is still seeking financing for parts three and four, based on how the first film in the series performs at the box office.
