As a child I used to listen to my parent's records. Many were 78 rpm discs that we played on the old RCA console, and later my father (who worked at RCA in Camden, NJ) added a turntable to play 33 and 45 rpm records.
One of those old records was the soundtrack to Lili (1953). Leslie Caron (b. 1931) was the star. She was 22 years old when she made this movie, playing a 16 year old girl. Her first film was An American in Paris (1951) with Gene Kelly (1912 - 1996) and is certainly the film she is most remembered for. Lili was her fifth film.
Mel Ferrar (1917 - 2008) played one of the love interests, the puppeteer. He is an accomplished actor/director/producer with 105 roles on IMDb. He was married for a time to Audrey Hepburn. Lili was his seventh film. Look for him in later hits; The Longest Day (1962), Sex and the Single Girl (1964), and on TV in "Falcon Crest."
