What caught Amanda's ear were the couple of references to Louise Brooks in the episode on John Gilbert and Greta Garbo, which was part of a seven part podcast on MGM. Give a listen here.
I recommend checking out the entire MGM series, which contains episodes on Jean Harlow, William Haines, Buster Keaton, Marion Davies and others. Earlier podcasts include episodes on John Wayne, Marlene Dietrich, Charlie Chaplin, Carole Lombard, Orson Welles, Kay Francis, Audrey Hepburn, Theda Bara, Humphrey Bogart and Lauren Bacall, and other stars of interest to those interested in Louise Brooks and early Hollywood. There are also episodes on Howard Hughes, Frank Sinatra and even a multi-part program on "Charles Manson's Hollywood."
