Near the end of the decade, Kellerman guest-starred in "The Invaders" in the episode "Labyrinth" (1968), she also played the severely beaten (and only surviving) victim of Albert DeSalvo in "the Boston Strangler" (1968), and Phyllis Brubaker (Jack Lemmon's materialistic wife) in "The April Fools" (1969). She turned down a role in Paul Mazursky's "Bob & Carol & Ted & Alice" (1969). She played Eleanor in the "Hawaii Five-O" episode "The Big Kahuna" (1969). In a 1971 "Life" magazine interview, Kellerman remembered her television years: "It took me eight years to get into TV—and six years to get out. Frigid women, alcoholics they gave me. I got beat up, raped, and never played comedy."
