Zack Snyder's action-packed sword-n-sandals smash 300 recently made its 4K Ultra HD debut courtesy of Warner Bros. Home Entertainment. In addition to revamped 4K HDR visuals, the film's soundtrack has been remixed in Dolby Atmos, while a bundled Blu-ray disc packs in over three hours of bonus features, including a director's commentary. We have five copies of the 300 4K Ultra HD Blu-ray up for grabs.
