Sometimes the most an actor could hope for with a film career is a single moment that places them in the firmament of entertainment history. For Annette Charles, she earned her place with a brief, but iconic turn in the screen version of "Grease" (1978). Charles enjoyed a torrid dance sequence as the sultry "Cha Cha" DiGregorio opposite John Travolta's Danny Zuko in the film, which went on to become one of the most popular movie musicals of all time and a perennial for young and old viewers alike. Though the success of "Grease" failed to translate into stardom for Charles, she enjoyed a lengthy run on television in the years that followed before leaving the business to become a speech professor. Despite leaving show business for a more anonymous life, Charles remained the once and future Cha Cha for generations of starry-eyed moviegoers.
