The essence of baseball is the primal battle between the pitcher and the batter, a magical moment only 396 milliseconds in the making. The mysteries and memories of baseball s greatest heroes are revealed in Fastball, as it features interviews with dozens of former players, from legendary Hall-of-Famers to up-and-coming All-Stars, including Hank Aaron, Nolan Ryan, and Derek Jeter, with narration by Kevin Costner (Field of Dreams). Fastball is peppered with archival footage of baseball s greatest moments, plus original high-speed 4K footage and motion graphics that unlock the secrets hidden within a ball traveling over 100 mph. While players, historians, and scientists might disagree on who was actually the fastest pitcher in history - and yes, the film does the physics and concludes with a clear verdict - Fastball tells the story of the game itself.
