Pregnant actress Angelina Jolie is apparently keen on starring in Sin City 2 after she gives birth to her twins.

Jolie is thinking of acting in Sin City 2 because she is interested in what director Frank Miller will come up with next. And she wants to do more action movies after having starred in the Lara Croft movies.

Jolie loved the 2004 release of the comic book and Miller is keen to have her be a part of the movie as well. He already has a character in mind for her to play.

The actress said: "I found the first Sin City impressive, but I don't know what they're going to do with the next one to make (it) as original as the first one. I'd be curious. I think he's (Miller) a genius."

The first Sin City was released in 2005 and starred Jessica Alba, Bruce Willis and Elijah Wood.
