Which real-life son of Sylvester Stallone played Rocky's son in Rocky V?

Sylvester Stallone's real-life son Sage Stallone played Rocky's son in Rocky V. He portrayed Robert “Rocky” Balboa Jr., Rocky and Adrian's only child in the film.

Rocky V, released in 1990, was Sage Stallone's acting debut. The story follows Rocky after financial problems and brain damage force him to retire. While Rocky trains the young boxer Tommy Gunn, his own son struggles with neglect, bullying, and the upheaval caused by the family's loss of wealth. Sage's casting gave the father-son conflict an unusual real-life connection.

Sage Stallone was Sylvester Stallone's elder son with Sasha Czack. He later appeared with his father again in Daylight and worked as an actor, filmmaker, and producer. A frequent mix-up is confusing Sage with Frank Stallone: Frank is Sylvester Stallone's younger brother, while Sage was his son. In later Rocky films, Robert Balboa Jr. was played by different actors as the character aged.
