Lani O'Grady is best remembered as Mary, the braniac med student daughter on the classic '70s dramedy Eight is Enough. In real life, Lani hailed from a famous family herself, being the sister of Don O'Grady of My Three Sons fame. Lani's career didn't get off to the smoothest start, though. She was featured in a few downer television productions, such as The Headmaster and Cage without a Key before her feature-film debut in Massacre at Central High (1976). The only thing massacred in that was Lani's clothing. She let loose her bountiful, bouncing breasts for a nice, long topless scene that would prove to be her only. Aside from her various Eight is Enough reunions, she more or less quit acting after The Kid with the Broken Halo (1982) to pursue work as a talent scout. Takes one to know one.
