Sage was our first child and the center of our universe and I am humbly begging for all to have my son’s memory and soul left in peace.”

InRocky V, Sylvester Stallone’s character is back where he began, on the streets, and attempts to regain his former glory by training a new protege, Tommy Gunn. The film portrays a conflicted son, Robert Balboa, who feels neglected by his father in favor of his career. Unfortunately, Stallone’s real-life story is not much different from theRockystory. In fact, he admitted drawing inspiration from his own life forRocky V.
While Stallone was able to mend his relationship with his son on-screen, theDemolition Manactor painfully confessed that he couldn’t achieve the same in real life. Stallone shared in his Netflix documentary,Sly:
“I try to take something that actually is what I wish I had done in real life, but I wasn’t able to do that in reality. And so, quite often, I would do it theatrically, magically. […] You know, unfortunately, you put things before your family, and the repercussions are quite radical and devastating.”
