The And God Created Women star rose to fame in the 1950s and '60s before retiring from acting in the '70s and devoting her life to campaign for animal rights.
Newman is reportedly working on a Bardot movie with King in the lead role, but the veteran star claims she has not been told about the biopic and has warned she would never authorise such a film because "no one" can portray her accurately on screen.
The 75 year old says, "A film about my life? But I'm not dead! They wouldn't dare do it without talking to me. If they do sparks will fly.
"I don't agree to a film about me without me having been warned and without me agreeing on who will play my part... There is no one who can do it. They have their own personality, but they don't have mine...
"I have heard nothing about it and there is no question of doing anything about me without my agreement."
