Katniss culture

The internets are abuzz with casting conjecture about The Hunger Games movie (which is moving ahead, supposedly, though never count your chickens, as they say).  In that context, I noticed that there seems to be a lot more women archers suddenly appearing on imdb. 

Late in December, the site featured a promo for Your Highness with Natalie Portman holding a bow.  This is a comedy, a period satire, but still. 

Just a few days later, the site featured another promo, for a movie called Hanna, with Saoirse Ronan (best known for Atonement and The Lovely Bones), as a girl raised to be an assassin by her ex-CIA father (Eric Bana).  It's not a period movie, but it's set in the "wilds" of Finland, which is close enough.

These 3 movies have very little in common besides their female sharpshooter, but it seems like more than pure coincidence.  Just sayin'.
