"Smokin' Aces" writer and director Joe Carnahan has updated his official blog with a blurb that director Robert Rodriguez showed him some clips from Sin City 2:

Robert Rodriguez stopped by the office yesterday and showed me what may become the teaser for Sin City 2 and HOLY SH*T is it something. I don't want to let any cats out of any bags, so all I can say is there's not a hetero male moviegoer alive that's not going to deeply DIG that spot. Remember, he's doing A Dame To Kill For and brother has he got it. That guy's enthusiasm for filmmaking is infectious too. A solid bloke and a good soul.

No word on when Sin City 2 would arrive in theatres!
