We approve of this casting. Boy howdy, do we.

It's been swell and all hearing that Jessica Alba, Mickey Rourke and even Bruce Willis will be back for the "Sin City" sequel, and it's been nice to hear about new cast members like Josh Brolin, Jamie Chung and Joseph Gordon-Levitt. But none of that makes for the casting news we've really been waiting for.

Now we have it. Eva Green, the impossible gorgeous Bond Girl of "Casino Royale" and the oft-naked cinephile of "The Dreamers," has been cast in the title role of "Sin City: A Dame to Kill For," according to Variety.

Green will be playing Ava Lord, a woman shaped by "every man's most glorious dreams come true and every man's darkest nightmares," according to Miller himself. She makes men do stupid, stupid things (especially Josh Brolin's Dwight, a man who really should've used his brain instead of his you-know-what). And she's going to look amazing both in and out of her femme fatale wardrobe.

Okay, you've got us: We're officially psyched for this movie now. It doesn't matter that it will have been eight and a half years since the first "Sin City" once the sequel finally hits theaters — it was worth the wait.

We're now counting down the days until October 4. 248 to go ...
