Her 1958 film The Bride and the Beast (1958), written by Edward D. Wood Jr., was released on DVD, newly remastered, in the spring of 2002 by Retromedia. VCI's later DVD release of the movie featured an audio commentary with Austin, supporting player Slick Slavin, gorilla movie expert Bob Burns and interviewer Tom Weaver.

With the advent of Cinemascope, Twentieth Century-Fox sent a half-dozen preview scenes of How to Marry a Millionaire (1953) to distributors worldwide showcasing the new process. Austin played the nearsighted "Loco" in these previews, with the original cast (Betty Grable, Lauren Bacall, David Wayne) playing their parts. In the completed film, Marilyn Monroe played the role of "Loco", with Charlotte playing the role of "Ding-Dong". Austin played the role of "Loco" again in the pilot for the TV series "How to Marry a Millionaire" (1957). Barbara Eden played the role in the final series. All cast members were replaced (with the exception of Lori Nelson), as was the director, John Rich (of "All in the Family" (1968)) fame.
