Rocky V (1990)—In the aftermath of his fight with Ivan Drago, Rocky Balboa is diagnosed with brain damage and is forced to retire from the ring. Additionally, the Balboa fortune is all gone due to an unscrupulous accountant. Rocky’s family returns to their old neighborhood: Adrian returns to the pet store she used to work at, while, in a subplot, Rocky (Robert) Jr. (played by Sylvester Stallone’s real son Sage) deals with bullying at his school and Rocky re-opens Mickey’s old gym. While training other boxers, Rocky meets a young, hungry boxer named Tommy Gunn (played by real-life fighter Tommy Morrison) and begins training him which results in a strained relationship with Robert. Unfortunately, as Tommy begins his rise to fame under Rocky’s wing, a sleazy fight promoter named George Washington Duke convinces Tommy that Rocky is holding him back and Tommy leaves Rocky for Duke. After Tommy wins the heavyweight title, he makes a short speech thanking Duke, and is met with jeers and the familiar chant of “Rocky” from the crowd. Seething from this insult, as well as being called by publicists as “Rocky’s robot” and being told that he’s “no Rocky Balboa,” Tommy decides to seek out his former mentor for a final showdown. Rocky starts to walk away from the public challenge, but Paulie decides to let Tommy have a piece of his mind about how Tommy has treated Rocky after which Tommy punches Paulie. Rocky then challenges Tommy outside. The two proceed in a violent bare-knuckle street brawl, which Rocky wins. Rocky then proceeds to punch Duke for harassing him. In the end, Rocky and Robert reconcile as they run up the steps as father and son. (source: wiki)
