Linda Hayden

She actually appears in several older horror movies, most which more or less have cult following (Madhouse, Taste the Blood of Dracula, House on Straw Hill (Video Nasty))

She also appears in that horror movie with Elizabeth Taylor, this it's called Night Watch, but it might have different titles. It's worth the watch tho, if I remember it correctly it has good atmosphere and few creepy scenes.

Chilone, see Expose aka Trauma. And it's a good movie, too.

She had just turned 18 when released, so was 17 during filming. In Baby Love she was 16.

A couple of more horror movies she turns up in during the 1970s are:-

Vampira (1974)
Queen Kong (1976)

Although both of these are comedy horrors.
