Jessica Alba believes that it's not a case of if Sin City 2 goes ahead but when.
The actress starred as Nancy Callahan back in 2005, alongside Bruce Willis, Mickey Rourke and Clive Owen.
And while there has been talk of a sequel for the last couple of years there is nothing set in stone. But the actress believes that it will go ahead.
Speaking to The Playlist the actress said: "We (director Robert Rodriguez and I) both love doing it, and we'd like to do it again - it's just kind of, you know, a matter of time I think.
"We were just talking about that actually in Austin, so we'll see. We kind of talk about Sin City every now and again, it comes up."
Alba is back on the big screen this week as she joins the cast of Meet the Parents in Little Fockers.
The movie is the third in the series and she joins cast regulars Ben Stiller, Robert De Niro and Teri Polo.
