Slender, gentle-featured lead and supporting actress of the 1960s and 70s, most typically in nonglamorous roles. After experience as a model and acting training under Lee Strasberg and others, Hackett gained notice off-Broadway with her award-winning work in "Call Me by My Rightful Name" (1961).

Hackett's quiet intensity suited her well for a TV adaptation of "Rebecca"
