Here you'll find a brief rundown of Audrey's film appearances. Her major television productions are listed below, and her two stage plays are listed beneath that. For more information on a film, click on its title (if there is a page for it yet). I also highly recommend visiting her IMDb page, which includes every television appearance, including all of her Oscar visits and some impossible to find variety show appearances.
