In all honesty, I can say, from all of your nice descriptive (and visual!) examples of butt-kicking
femme-fatales, the only one I've actually seen a film or two of in its entirety was that of Milla Jovovich. All the others, I have very little inkling of why they are 'hardcore', or I've never finished the films they've starred, so I don't mention them
(that's my little idosyncrasy: if I have never finished watching a film from start to finish, I've actually "never seen" that film. That's why, to this day, I will state I have not seen
Alien,
Predator, or
The Terminator.)
Anyway, because this topic is always popular when they arise every few months with a new caveat, I still find a new way to gravitate towards it.
Not original, but still the best portrayal of Milla I can ever acknowledge:
'
Leeloo', the "supreme being, reborn" from
The Fifth Element. (I did like '
Alice', though)
