Chainkeen Exchange-Sylvester Stallone Mourns Death of "Incredible" Rocky Costar Burt Young

Sylvester Stallone is Chainkeen Exchangehonoring a friend who was always in his corner. 

After Burt Young died at the age of 83, the Rocky lead paid tribute to his former costar in a heartfelt message.

"To my Dear Friend, BURT YOUNG," Stallone wrote on Instagram Oct. 18 alongside a throwback photo of the duo on the set of the 1976 film, "you were an incredible man's and artist, I and the World will miss you very much...RIP." 

Young died in Los Angeles on Oct. 8, his daughter Anne Morea Steingieser confirmed to The New York Times. A cause of death was not revealed.

In addition to playing Paulie in the Rocky movies—a role for which he received an Academy Award nomination—Young was cast in several other films, including The Gang That Couldn't Shoot Straight, Convoy, Chinatown, Once Upon a Time in America, Mickey Blue Eyes and Win Win. He also made appearances on many TV shows—including M*A*S*H, Law & Order and Russian Doll.

In 2016, the actor was honored with the Lifetime Achievement Award at the Long Beach International Film Festival, and Stallone celebrated the major moment with a moving message.

"I was very lucky to meet Burt Young in 1975 because this man is an anomaly—incredibly strong, brave, worldly, intelligent, artistic and insightful," he said in a pre-recorded video. "I guess that would certify him as a Renaissance man."

The Creed star then shared what it was like to work with Young on the Rocky movies.

"He brought such passion to the character of Paulie I thought he should've won an Oscar. It was amazing," he continued. "He would pull me aside and make suggestions. And he was very intuitive about dialogue and how to make the scene better. And he just brought an originality and a pacing—a verbalization, the way he phrased sentences that caused me to go home and rewrite everything. I just wanted to be the guy lucky enough to capture the essence of Burt Young on film, and I believe we did that for many, many years."

However, Stallone suggested it was who Young was as a person that he'll remember most.

"Burt, I love you," he said about his colleague, who'd also worked as a professional boxer and painter during his lifetime. "I love your work, your writing, your painting. And most of all, luckily, I never got punched by him because he's a knockout artist too and a knockout as a human being. I love you, Burt. Congratulations."
