A documentary outlining Sylvester Stallone's experiences playing the iconic Rocky Balboa in the original "Rocky" movie comes out at the beginning of June.
"40 Years of Rocky: The Birth of a Classic" is written and produced by Derek Wayne Johnson.
"The documentary is a golden nugget for 'Rocky' fans and casual audiences alike," Johnson said in a statement. "It's a charming piece of film history narrated by Rocky himself, Sylvester Stallone, and will give audiences an intimate, and at times, emotional experience."
He continued, "We’re proud of the film, and audiences can expect new stories and new footage that they’ve never seen before in a blend of director John Avildsen’s home movies, rehearsal footage, and behind-the-scenes footage from the making of the ultimate underdog film."
This isn't the first time Johnson has worked to examine the classic "Rocky" film. In 2017, he directed "John G. Avildson: King of the Underdogs," which is a documentary that explores the director of both "Rocky" and "Karate Kid."
His upcoming venture, "Stallone: Frank, That Is," will chronicle the life of Frank Stallone, Sylvester Stallone's brother.
"40 Years of Rocky: The Birth of a Classic" is set to arrive on iTunes/AppleTV and Amazon on June 9.
