"I know I'll probably make a fool of myself if I make another 'Rocky' film after turning 60," the 63-year-old actor-writer-director told Germany's Tele5. "I also know there's gonna be a lot of criticism. Even my wife says: 'Don't do it. You're embarrassing the kids.' But I told her, 'If I don't try I'll be a really unhappy man.' You have to do it. Artists like me have to go through the dark over and over again."
"Rocky Balboa," the sixth installment in the boxing franchise, was released in 2007. A fifth "Rambo" movie, featuring the other titular big-screen hero Stallone is famous for playing, is expected to start shooting next year, Total Film reported.
