Anson Williams – 70

Speaking of the Happy Days series, Anson Williams surely couldn’t be missing from this list. He was, after all, the person who got to portray the character of Potsie Webber for so many years. He moved on to be part of other series like Baywatch. He has also built quite the portfolio as a director with projects such as Melrose Place, Beverly Hills 90210, and Sabrina the Teenage Witch. An episode of The Odd Couple in 2016 served as his last acting stint. Even though he hasn’t acted in a while, the now-70-year-old Williams took part in the 2019 documentary series titled The Very Very Best of the ’70s.
