Over the course of her three decade career in show business, Susan Dey was interviewed many times. Some interviews have probably been long forgotten, though others still exist and can be seen today. Susan Dey interviews with obnoxious chat-show hosts David Letterman and Rosie O'Donnell (Dey was on Rosie's show twice) are two of the most popular examples.
In December of 1977, Susan Dey was interviewed by both Mike Douglas and Merv Griffin (presumably related to her breakthrough role in the movie First Love that year). In 1989, Dey appeared on CBS This Morning and in 1993 she did Good Morning America. 1991 saw the actress as a guest on The Arsenio Hall Show. Many more televised interviews likely exist and hopefully one day fans will have greater access to them!
