Beautiful Siobhan McKenna is sadly no longer with us, a victim of lung cancer taken too soon on November 16, 1986. She is best known for her role as Anna in the sweeping romantic drama Doctor Zhivago (1965). Though a PG-13 rated film, back then that could often mean full-frontal nudity. Again, sadly, in this case it does not. Siobhan never got skinful onscreen, except for a hot scene from Doctor Zhivago that finds her topless in bed but lying on her breasts. Now we’ll never know what the good doctor was so hot and bothered about.
