I have asked this question on every message board that I can remember. No one has been able to answer. I am assuming the movie is from the ‘70s. All I can remember is there was a lady that was pregnant, she wanted an abortion or to not be pregnant anymore so her people (I can’t remember if they were cannibals or a tribe or what) had her lie down under a cliff and they threw a huge boulder over onto her. It disturbed me as a kid and I was born in ‘78. Thank you so much in advance.
