Most people know F. Scott Fitzgerald as one of the deans of the lost generation and an icon of the jazz-age. But toward the end of his life, in the late 1930's, Fitzgerald was also a writer for MGM studios, and these stories represent brilliantly and tragically this period of his life.
Through the eyes of Fitzgerald's Pat Hobby, Hollywood hack writer, we see a different side of golden age tinseltown, where an extraordinary number of talented writers and artists migrated to in the 1930's and 40's, only to butt their heads against militant mediocrity and the "studio system." As an archetype, Pat Hobby stands in for them brilliantly.
