IGN Movies reports that director Robert Rodriguez, rumored to be tired of waiting for Angelina Jolie's schedule to open up a "Sin City 2"-sized hole, may have begun efforts to secure the services of another actress for Jolie's role.

Which actress? Well, these are rumors, so the speculation is still suitably wild -- names being floated at the moment include Rachel Weisz, recently seen in "The Fountain," and Rodriguez' "Grindhouse" gun moll Rose McGowan. Seeing as how the sequel doesn't look to be starting production until next year at the earliest, we may be hearing variations on this one for awhile.
