The Creed star received a standing ovation when he won Best Supporting Actor at the 2016 Golden Globe Awards for the critically-acclaimed sequel and reboot of the Rocky franchise, also starring Michael B. Jordan.
"Last time I was here, that was 1977," said the 69-year-old actor, referring to his last nomination for the original Rocky film. "It was a long time ago. It’s like a different, different situation and the view is so beautiful now."
The actor also paraphrased some Creed wisdom, telling ET's Instagram, "The guy you're fighting in the mirror, is going to be the hardest opponent you're ever gonna fight. Inside the ring and outside. It's you against you."
Despite all his acclaim, Stallone remained humble, even admitting in the press room that his kids don't get what the big deal is, saying, "They never really knew who I am."
