I get it. At least I get some of this excerpt from Yahoo! Movies:
The singular is femme fatale; the plural is femmes fatales. (Both words need an S because it is French and that’s the way the French like their plural nouns and adjectives.) The queen doesn’t get a capital letter unless you also use her name (so, it’s the queen, but Queen Elizabeth). As for that bit of nonsense about something being “praised as the highest praise as”? I have no idea what that’s all about.
