Horizon: An American Saga – Chapter 1 (June 28)

Kevin Costner directed, co-wrote and stars in Horizon: An American Saga. It’s coming to audiences in two parts — Part 2 hits theaters on August 16, and it’ll be interesting to see how receptive audiences will be to this two-parter. Recently, Mission: Impossible: Dead Reckoning presented the first of a two-part story, but when there was audience blowback, the first movie's name was changed to remove "Part One" and the second film, which doesn't yet have a title, has been delayed to May 2025.
