Dear TellyTalk, I'm a binging addict of Peyton Place and I just can't help myself...
Either way, I've now gotten to the point where I assume the "Allison replacement" aka Leigh Taylor-Young is introduced - Norman even proclaims when he first sees her legs that "it's Allison!". Very subtle, show.
Also, having started watching Dark Shadows (which started airing in June 1966) a bit I'm slightly amused with how some of the slightly gothic elements from that show seems to have been introduced into Peyton Place - first you had Ann, her fascination with the cliff and the water below which mirrors of course the suicide cliffs in Dark Shadows and now you have Rita and Norman exploring a creepy cottage only to find... the Allison replacement? I don't know for sure yet, but I think it must be Leigh Taylor-Young that's being introduced.
