4. Queen of the Jungle
Actor Tippy Hedren is perhaps best known for her role in the Alfred Hitchcock classic The Birds, but Hedren led an incredible life. In addition to being an accomplished actor and model, she was also instrumental in the development of Vietnamese-American nail salons in the United States, traveled around the world to set up relief programs for natural disasters, and was an avid animal rights activist.
She had a particular soft spot for great cats. At one time, she had several adult male lions living on the grounds of her Hollywood home. Hedren and her husband at the time, director Noel Marshall, even used the lions to produce a movie called Roar! in 1981. The set of the film was notoriously dangerous, and eventually, Hedren moved the lions to a nature reserve she founded.
