The essence of baseball is the primal battle between the pitcher and batter, but the magic of the game arises from that confrontation, only 396 milliseconds in the making. The mysteries and memories of Baseball's greatest heroes are revealed in "Fastball," featuring interviews with dozens of former players, from legendary Hall of Famers to current All-Stars. Based on the original idea by the film's producer, Thomas Tull, who also produced the Jackie Robinson biopic "42," "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.
