Kevin Costner's new western epic “Horizon: An American Saga — Chapter 1” is the kind of film that begs the question: How did this get made? But we already know, because part of the film's lore is that producer-director-star-co-writer Costner staked the funding himself, at great personal risk.

In this case, the mighty is Kevin Costner, and he hath not only fallen but hurtled over the edge with Horizon: An American Saga — Chapter One. The new three-hour behemoth, released Friday, is the first of a four-film epic Western that Costner says he's wanted to make since 1988.
