Lilith is a reference to the character from Jewish folklore of Adam's first wife, a demon who preys on single men, and is the daughter of Asmodeus.
The title "Femme Fatales" is not a correct French phrase. "Femme fatale" means "deadly woman", but "femmes" is the plural of "woman" in French. The word "fatale" is never made plural; there's no such word as "fatales" in French. The title, as is, would be translated "deadly women".
Jonathan Shields, the character played by Richard Kind, is a homage to Kirk Douglas studio executive in "The Bad & the Beautiful".
"Femme Fatales" was honored as an Official Selection of the 2011 and 2012 Sitges International Film Festival which showcased several episodes including "Behind Locked Doors", "Haunted", "Something Like Murder", "Help Me, Rhonda", "Libra", "Family Business" and "Extracurricular Activities".
The title "Femme Fatales" is based on the trademark for the magazine, Femme Fatales, a popular magazine devoted to "the lovely sirens of film, television, music and the web."
