Sage Stallone

Sage Stallone was born May 5, 1976 in Los Angeles, California, the elder son and first child of Sasha Czack and actor Sylvester Stallone. He was the brother of Seargeoh "Seth" Stallone, and half-brother of Sophia, Sistine, and Scarlet Stallone. He was the nephew of actor and singer Frank Stallone, and grandson of Jackie Stallone. He was the stepson of model and entrepreneur Jennifer Flavin.

Stallone graduated from Montclair College Preparatory School in Van Nuys, California, in 1993, and then studied filmmaking for a year at the University of North Carolina School of the Arts.

Sage Stallone's first television appearance was on the May 21, 1982 episode of The Tonight Show Starring Johnny Carson.

As a child, Stallone made a guest appearance on Gorgeous Ladies of Wrestling, a series that was promoted by his grandmother, Jackie Stallone.

Stallone made his acting debut alongside his father in Rocky V (1990), the fifth installment of the Rocky franchise, playing Robert Balboa Jr., the onscreen son of his father's title character. He also appeared with his dad in Daylight (1996). He subsequently appeared in low budget exploitation films.

In 1996, Stallone and film editor Bob Murawski co-founded Grindhouse Releasing, a Los Angeles–based company dedicated to the restoration and preservation of exploitation films such as Cannibal Holocaust and Gone with the Pope.

In 2006, he did not reprise his Rocky role in Rocky Balboa because he was working on his own film, Vic, his directorial debut. He also wrote and produced the film, which won the "Best New Filmmaker" award at the 2006 Boston Film Festival.

His last projects were appearances in Vincent Gallo's last two films, Promises Written in Water and The Agent. Both films were shown in main competition at the 2010 Venice Film Festival and in the Toronto International Film Festival. A photograph of Stallone as a young child beside his father appears in the 2015 film Creed, where it is stated that his character, Robert Balboa Jr., has since moved away to Vancouver.
