Pumpkinhead (1988) actress Cynthia Bain may bear a resemblance to Sigourney Weaver & another actor, actress or group from some movie, TV series, etc. I was not quite sure of. Connections: Lance Henriksen, who played android Bishop in Aliens was also Ed Harley in Pumpkinhead.
Alternatively, I thought Cynthia Bain may resemble actress Jane Fonda.
