Markie Post, best remembered for her role as the innocent, Princess Diana-obsessed public defender Christine Sullivan on Night Court, has passed away following a three-year battle with cancer.

Post joined the Night Court cast in season three and stayed until the end of the series' nine-season run. Sullivan served as the primary love interest for Judge Harold T. Stone, played by Harry Anderson.

In addition to Night Court, many remember Post as her role on The Fall Guy, the Lee Majors series about a stuntman who moonlights as a bounty hunter. Post played Terri Michaels, a bail bondswoman, for the final three years of the show.

Post teamed up alongside John Ritter for the lesser-known sitcom Hearts Afire, a political comedy that aired for three seasons in the early 1990s and welcomed guests from left and right like Rush Limbaugh and Hugh E. Rodham, father of Hilary Clinton. The noteworthy cast also included Billy Bob Thornton and Ed Asner.

On Scrubs, she found a recurring role as the mother of Dr. Elliot Reed (Sarah Chalke). Game show fans will remember her as a regular presence on The $100,000 Pyramid and Super Password. She had a small but memorable role in the 1998 hit There's Something About Mary as the mother of Cameron Diaz's titular character.

Post was born in the Bay Area, the daughter of a poet mother and a brilliant, renowned physicist. Richard F. Post held 34 patents — covering everything from nuclear fusion to particle accelerators.

Markie (full name Marjorie Armstrong Post) began her showbiz career in game shows, albeit behind the scenes, in the production team for Split Second and Double Dare (the CBS version, not Nickelodeon). Her chance in front of the camera came on Card Sharks, where she played a card dealer.

On the acting side, Post began her TV career with guest spots on CHiPs and Barnaby Jones. She was 70 years old.
