A new nonfiction book explores the behind-the-scenes story of Rocky's creation 50 years after the 1976 film's release. Going the Distance: Stallone, Philly, and the Story of Rocky, published by St. Martin's Press and available today, November 10, examines how Sylvester Stallone went from struggling actor to Hollywood star through the making of the original film.

Author Mike Sielski, a longtime Philadelphia Inquirer columnist and former Wall Street Journal reporter, conducted extensive research including interviews with people directly involved in the production. Producer Irwin Winkler and composer Bill Conti are among those featured. The book investigates the circumstances surrounding Rocky's development, the personal experiences that inspired the character, and the influence of real-life boxers like Rocky Marciano and Chuck Wepner.

Sielski also challenges familiar stories about how the movie came together, uncovering lesser-known details. He was previously named America's top sports columnist by the Associated Press Sports Editors and wrote The Rise: Kobe Bryant and the Pursuit of Immortality.

The book is available in hardcover, Kindle eBook, Audible audiobook narrated by Kevin Earlywine, and physical audio CD editions.
