Edwards' career began in the 1940s as an actor, but he soon turned to writing radio scripts at Columbia Pictures. He would later begin to write or direct movie such as; "Experiment in Terror", "The Great Race", and the hugely successful "The Pink Panther" movie series with the British comedian Peter Sellers. Often thought of as primarily a director of comedies, he also directed drama movies such as; "Breakfast at Tiffany's" and "Days of Wine and Roses". His greatest successes, however, were his comedies, and most of his movies were either musicals, dramas, comedies, or horror.
