Lorna McGrath is great. I've always loved Arlene Martel in any scene, but her vulnerability in Greenhouse makes me want to just grab her and......wait, strike that from the record. I love Marcy, the Australian who was impressed with Harold's "superwatch". Imagine if you showed her an iPhone. Vanessa from Nightlife has that same "vulnerability". She's stunning and perhaps my all-time favorite Columbo gal. You made a nice list.
A while back somebody made a list of the hottest men, but guys can't really judge other men the way women can judge each other. Women admire talent, intellect, etc. Men are mainly attracted to the physical.
