Before Sean Penn was a three-time Oscar winner, he was an extra on an episode of Little House on the Prairie that his father, Leo Penn, directed. How cute was the 14-year-old in that 1974 episode?
Before Martin Kove was a cop on Cagney & Lacey, he was doing illegal things on Edge of Night. Even when he was 34 in that 1981 episode, he was so good at being bad!
Before Corey Stoll was fighting Vampires on The Strain, he almost fought a man at a bar on All My Children. He looks the same now as he did when 27 in that 2003 episode.
