In 1982, Brennan had just finished dining with Goldie Hawn when she stepped into the path of an oncoming car. She suffered severe injuries to her legs and jaw, had an eyeball wrenched from its socket and broke multiple bones in her face. That led to an addiction to prescription pain pills, followed by a dependence on antidepressants and antianxiety medication.
She made her return with a role in the TV comedy Off the Rack in 1984. Other TV credits included Will & Grace, 7th Heaven, Strong Medicine, Lizzie McGuire, Touched by an Angel, Mad About You, Veronica’s Closet, Nash Bridges, ER, Walker, Murder She Wrote, All-New Dennis the Menace, Tales from the Crypt, Home Improvement, thirtysomething, Blossom, Newhart, Magnum PI, The Love Boat, Kojak, McMillan & Wife, All in the Family, and Rowan & Martin’s Laugh-In.
