I did once read the book "The G-String Murders" and want to make
a few things clear: in the book the character name of Dixie Daisy is
"Gypsy Rose Lee". If I recall correctly, the book was amusing but
thin and the movie is a considerable improvement on it.
Also, if I recall correctly, Gypsy was an "intellectual" stripper who
showed a minimum of skin and so the movie was not inaccurate
in that respect.
Stanwyck showed, not only versatility, but a considerable amount
of warmth in the part of Dixie, qualities which the original Gypsy
also had. (I had a friend, now deceased, who worked with Gypsy
for a time and he spoke about her a great deal and with much
admiration.)
I thought Michael O'Shea was excellent as the comic Biff and Pinky
Lee fit into the backstage ambiance beautifully. The "mystery" was
of almost no interest but this is besides the point. The
photography was also very interesting and added to the sleazy
backstage atmosphere.
