Michael Rooker, a co-star in Kevin Costner's 'Horizon: An American Saga – Chapter 1,' defended the film following its box office failure, emphasizing it as 'real cinema' with a three-hour runtime challenging modern movie norms. Costner invested $38 million in the movie and its upcoming sequel. Rooker criticized the trend towards shorter films influenced by platforms like TikTok and urged audiences to appreciate the depth of storytelling in 'Horizon,' despite poor reviews. The Western epic, featuring an ensemble cast, aims to engage viewers with a rich narrative spanning multiple films directed by Costner.
