If you've got a couple of minutes to indulge me, have a look at the following link and then come back with who you think had the greatest decline in SMV.
My call is Kim Novak - she was like a high 9 - but hit the wall like a ripe tomato fired from a crossbow.
And in general the Men seemed to have fared much better. And note I think Raquel Welch is photoshopped.
Lol, should've archived this, with all the shitty ads on that site...
Some of those are no longer alive, now, too...
Going only by the men, Hoges looks like the walking dead, and Shatner has been Jabba since like, the 80s, so... Eh.
But nominees for non-actresses who are still in great nick? Emmylou Harris, Susanna Hoffs and Grace Slick (from Jefferson Airplane) until fairly recently...
Oh, and in terms of hitting the wall - don't forget Ursula Andress, lol. Man, she... Absolutely destroyed her face. Much like Novak did.
Oh sorry I didn't get the ads because of my blocker so wasn't aware. I noticed Harry Belafonte as he only just died. Some of the people I didn't even know at all - must be a fairly USA-centric list
