I don't recall Rose McGowan being a "scream queen". I remember her being a bad ass with alternative interests. The closest she ever got to "screaming" was the prom scene in Jawbreaker.
One of the originals, if not the original: Barbara Steele. Too many on this list were in 1 or 2 horrors. Not every woman who screams in a horror film is a scream queen.
This list is a joke! Sure, it started off good but then descended to any female actress who starred in ONE horror movie! Where are Brinke Stevens, Michelle Bauer, (both of which starred in many, MANY horror movies with Linnea and are considered the first women who actually coined the term 'scream queen'), Linda Blair, Danielle Harris (both who started their careers early in the horror field) and Barbara Steele (who was in so very many horror movies). And if you're going to include women who starred in one horror movie, then why not one of the earliest? That is to say, Jamie Lee Curtis' mother, Janet Leigh.
