　　If you__APOS__re wondering about this film and why it__APOS__s dubbed in Italian, then read the following comment from IMDb:
　　I have always wondered about the disappearance of __QUOTE__Deluge__QUOTE__. Why for so many years, seemingly since it__APOS__s release in 1933, this film vanished from the face of the earth. After seeing it, courtesy of the efforts of Mr. Wade Williams __AMPERSAND__ Co., I__APOS__m still puzzled, but I have a theory. In 1933, __QUOTE__the code__QUOTE__ was enacted that pretty much took care of sex and violence in Hollywood. While not an explicit film by any means, __QUOTE__Deluge__QUOTE__ does deal fairly frankly with sexuality, lust and rape. I wonder if RKO discovered they had a film that they could not re-release, much like the fabled lost Warner Bros. comedy __QUOTE__Convention City__QUOTE__. It__APOS__s a shame for, while it is a dated film, I find it quite unique and surprising for it__APOS__s era and a fairly successful attempt to create something different in an era when films were already becoming cookie cutter by-products of the studio machine (not that many of those cookies aren__APOS__t tasty, mind you). And even though the only available copy at this writing is dubbed into Italian, I don__APOS__t find that a hinderance. An excellent job was done in subtitling the film, and much of the film is visual anyway.
