Milo Ventimiglia is set to play Sylvester Stallone's adult son in
Rocky VI, says the Hollywood Reporter.
The feature is about the mythic Philadelphia boxer, Rocky, who has long since retired but is drawn back to the ring one last time. He is challenged by a powerful new champion, by personal tragedy and ultimately by himself.
Rocky's son, Rocky Balboa Jr., was first introduced into the franchise in 'Rocky II', when his birth was a pivotal moment in the film.
