In 1971, TIME photographer Michael Rougier spent time photographing actress Tippi Hedren, her daughter Melanie Griffiths, and their 400 pound pet lion, Neil at their California home. Though known as a gifted actress, Hedren was also a predominant animal-rights activist and conservationist with the Roar Foundation, which advocated for big cats. These images document the obviously affectionate relationship between Hedren and Neil and offer a glimpse into a unseen aspect of her life. Rougier perfectly captures the playfulness not often associated with these animals, fully supporting Hedren's conservation efforts.
