Fastball, a baseball documentary three years in the making, debuted Monday night at the Tribeca Film Festival. Produced by Thomas Tull and directed in association with Major League Baseball by Jonathan Hock (director of an impressive slate of award-winning 30-for-30 films on everything from the NC State Wolfpack’s 1983 NCAA tournament run to forgotten football player Marcus Dupree,) Fastball celebrates baseball’s signature pitch and aims to definitively answer the age-old debate: who threw the fastest fastball of all-time?

The resulting documentary, narrated by Kevin Costner, is a fascinating dive into the history, physics and mythology of the game – full of gorgeous slow-mo pitching footage, interviews with Hall of Famers from Goose Gossage to Bob Gibson to Hank Aaron, a rare appearance by fastball cult figure Steve Dalkowski, and enough chalkboard math equations to earn the viewer a Ph.D. in baseball science.
