2024's upcoming Western, Horizon: An American Saga, has a very good chance at beating a Kevin Costner record held by a movie from 1990. Horizon, which is set to focus on America's expansion before and after the Civil War, is being billed as a two-part theatrical event. Rather than release each part in separate calendar years, Horizon is taking a different approach, releasing Chapter 1 in June 2024, with Chapter 2 arriving just seven weeks later. While Costner is obviously the big draw as Horizon's lead character, the project's supporting cast is nothing short of noteworthy.
