I'm not sure about best overall screamer although I do adore Nancy Barrett. . .I think **the** best scream of the entire show was Julia's in her bedroom with the breathing door when Barn was trying to drive her nuts. . its was one long horrible scream. . not Grayson's later oft-heard gasping scream. . .It was very reiminiscent of Stanwyck in the Nightwalker. . .I think i'll pop in the tape right now .. . of Julia i mean, clutching her bedpost and crying. .great DS stuff!
