"I have some news to share with you all. After working on Horizon for over a year and a half, and considering the challenges that come with it, I have come to the difficult decision that I won't be able to continue with Season 5 or any future seasons," Costner writes in his post.

"The experience that transformed me was something I loved and I know you loved it too. I wanted to inform you that I won't be coming back. Despite the wonderful relationship we've built, I'll catch up with you at the cinema."
