Hugo Haas was pretty much the salvation of the "femme fatale" in the fifties, as much of the female behavior became a lot more muddled.

So let's put that in context of the whole list--a few entries of which seem to open for some further discussion:

1/Veda Pierce, MILDRED PIERCE 14 (she'll get 15 points when she grows up)
2/Norma Desmond, SUNSET BLVD.<---can she plead the insanity defense?
3/Phyllis Dietrichson, DOUBLE INDEMNITY 15
4/Annie Laurie Starr, GUN CRAZY 14 (lost a point for being sympathetic at end)
5/Gilda, GILDA
6/Laura Hunt, LAURA
7/Kitty Collins, THE KILLERS<---not a femme fatale at all?*
8/Kathie Moffit, OUT OF THE PAST 15
9/Brigid O'Shaughnessy, THE MALTESE FALCON<---not a femme fatale at all?*
10/Alice Reed, WOMAN IN THE WINDOW
11/Vera, DETOUR 14 (Al was doomed with or without her)
12/Elsa Bannister, LADY FROM SHANGHAI 14
13/Cora Smith, THE POSTMAN ALWAYS RINGS TWICE 15
14/Ellen Berendt Harland, LEAVE HER TO HEAVEN<---not a femme fatale at all?*
15/Rose Loomis, NIAGARA <---"just" a cheating wife...
16/Kitty March, SCARLET STREET 13 (also the victim of a homme fatale)
17/Laurel Gray, IN A LONELY PLACE
18/Sherry Peatty, THE KILLING 13 (George was an easy target)
19/Helen Grayle aka Velma Valento, MURDER MY SWEET <---not a femme fatale at all?*
20/Jane Palmer, TOO LATE FOR TEARS 14
21/Madeleine Elster aka Judy Barton, VERTIGO<---femme fatale as woman-in-distress...oddly, lowers the score because "meta-peril" is not "true peril"??
22/Myra Leeds, PLEASE MURDER ME<---not a femme fatale at all?*
23/Debby Marsh, THE BIG HEAT
24/Lilith Ritter, NIGHTMARE ALLEY (1947)<---not a femme fatale at all?*
25/Coral Chandler, DEAD RECKONING <---not a femme fatale at all?*

Note the paucity of 50s films (shown in bold type.

Characters w/o any annotation--either a number score from Owen or a query about their status from me--are clearly NOT femmes fatales (though Gilda presents as one). That's five out of the twenty-five.

So are the ones annotated with my query not FF's, or are they ones whose overall intensity score simply doesn't rise to the level of a "13"? Please clarify, and from there we should be able to continue a bit further...
