It's easy to forget that the amazing Farrah Fawcett starred in the 1976 sci-fi feature film Logan's Run. She was only in one scene and played the character Holly 13 who worked at a receptionist at the "New You" face-change parlour. She was great as this duplicitous mentalist and when I first saw this as a little kid, seeing Logan getting his face sliced open with all those creepy looking lasers really shat me up good.
You really couldn't ask for a much more perfect spacebabe than this. Just havea really good look at the picture below and tell me she couldn't have pulled off Barbarella.
