When VHS was available in the late 80's or early 90's, I rented a copy from RKO video and was disappointed that most of that scene had been cut. She is stunning and the image will be burned into my memory for the rest of my life.
A 12 or 14 foot tall image of Bo's glistening wet body strolling up and out of the blue ocean directly towards the camera, into bright sunlight is one of the most beautiful images a person could ever imagine. Twenty-seven years later, I remember in vivid detail the scene of her coming out of the ocean in full-frontal nudity. From the standpoint of pure physical beauty of human form, Bo Derek was at her physical peak when her husband shot her for this film.
I was bored out of my mind except when Bo Derek found herself in a situation where she could shed her clothes. There were only a few people in the theater when the show started and several left as the movie dragged on.
Having seen '10' about a year earlier, and thinking Tarzan the Ape Man might be similarly funny and entertaining, I took the 45 minute drive from a very rural town in San Mateo County, California 'over the hill' to San Carlos to see a late night showing one Friday night in 1981.
