ROCKY MARCIANO's younger brother will act as a consultant on the first authorised biopic of the boxer's life.
Lou Marciano is working with scriptwriter Terri Apple on hard-hitting new movie Undefeated: The Rocky Marciano Story, which is to be directed by two-time Oscar nominee Mikael Salomon.
The younger Marciano is promising to reveal new details about his brother's life for the movie, which will chronicle the legendary fighter's life from childhood to his plane crash death in 1969.
Take a look back at October's inaugural event.
The film is expected to continue without Mendes' involvement.
