It takes a special kind of actress to convincingly pull off the role of a 'tough-chick'. Some, such as Michelle Rodriguez (one of my favourite actresses), are almost exclusively cast in such roles, and whilst it's clear she could beat the living crap out of any woman, and probably most men too, she doesn't actually do a great deal of arse-kicking in her films (not even in Girlfight). Others, such as Sigourney Weaver, particularly in her Ripley guise, prove themselves to be more than the helpless girly they initially appear and can rise to the occasion when needed.
However, the kind of female heroine that can not only take care of themselves but also lay waste to scores of bad guys whilst still looking good? That takes a special talent which goes beyond merely learning a martial art, sword-handling, or gun-play. They have to be good actresses, of course, but it's also an attitude or aura they project. You just know, even if they're only talking, that they could take out an entire room of sneering, gun-wielding goons in the blink of an eye and then continue chatting away as if nothing had happened. Some actresses look ridiculous trying to act tough, but for others it comes naturally. Here's my personal Top Five toughest:
Possible Spoiler Alert: this feature obviously assumes that you've seen the films in question so don't come whining to me if they ruin a film that you haven't seen yet!
5 - Trinity
The only lady on the list whose repertoire doesn't include a blade of some description, Trinity (Carrie-Anne Moss) makes up for it by being more than proficient at pretty much everything else! Okay, she has the rather sizeable advantage of being able to upload new skills and combat techniques directly into her brain almost instantly which is probably the only reason she's not higher on the list. That's far from the only thing that makes her a genuine tough chick though. She's an efficient and very creative arse-kicker and I can't see anyone but Morpheus or Neo standing toe-to-toe with her for more than a second, but all that aside, she'd be worth including simply for "Dodge This!"...
