Catherine Spaak (born in 1945) was the daughter of Charles Spaak who wrote the screenplay to Jean Renoir's film, La Grande Illusion. At 14 she made her film debut in Italy launching a career that included some of the more interesting European teen films of the early 60s.
There is a blog called La Calda Vita (named after one of her films) devoted to the actress. It's filled with commentary about her and her films, screen captures from those films, and other rare photos and articles.
