This book was a real disappointment. The vaudeville and "Follies" sketches reproduced here do not translate, as they were meant to be seen, not read. Ditto the endless treatments for proposed films. The radio scripts fare best, as they were written in dialogue form without stage directions, and if one has any familiarity with Fields and Edgar Bergen/Charlie McCarthy it's easy to imagine them giving voice to the material.
The correspondence is of some interest, though the first letters section (1880 - 1929) seems to be composed primarily of responses to his wife's constant requests for money, which quickly become tedious.
None of this material was created for an "intended autobiography," it's just a bunch of debris found in a basement and capitalized upon by Fields' heirs. Aside from being addressed by him in letters, Fields' contemporaries (Will Rogers, Florenz Ziegfeld, Eddie Cantor, Gregory Lacava, Jack Benny, John Barrymore) are all noticeably absent.
Field's companion/mistress for the last 14 years of his life, Carlotta Monti, is given particularly short shrift here. Her book, W.C. Fields and Me, BTW, while padded, is far superior to this effort, and paints a far more vivid portrait of Fields. (And I use the word effort loosely, as very little of it seems to have gone into assembling this mess.)
