9. Richard Masur (David Kane)
Richard Masur featured in pretty much every popular ’70s show there was – everything from The Waltons to M*A*S*H to Hawaii Five-0. But undoubtedly one of his most enduring roles has been as David Kane in One Day at a Time.
Still, since Masur’s days as Ann’s divorce-lawyer-turned-boyfriend, he’s more than kept himself busy. At present, for example, you can catch him starring as Buzz in the hit Amazon show Transparent. He’s also a board member of the Motion Picture & Television Fund.
8. Valerie Bertinelli (Barbara Cooper)
In One Day at a Time, Valerie Bertinelli played Barbara, the other daughter of Ann Romano. Barbara was the opposite of rebellious Julie, however – she was the dependable, wise-cracking kid of the family. And for her efforts, the talented Bertinelli won a Golden Globe Award for Best Supporting Actress.
