Following yesterday's news that Joseph Gordon-Levitt has joined the lead cast in Sin City: A Dame to Kill For, today we have word that Christopher Meloni is also joining the cast, and actor Josh Brolin is being considered for an unspecified role.

The actor, who will next be seen this summer in 42 and Man of Steel, is playing a Basin City cop, in what is described as a lead role. Sin City stars Mickey Rourke, Clive Owen, Jessica Alba, Rosario Dawson, and Jaime King are reprising their roles for the sequel. New cast members include Alexa Vega and Dennis Haysbert, who replaces the recently-deceased Michael Clarke Duncan as Manute.

Robert Rodriguez and Frank Miller are directing from a screenplay they co-wrote with William Monahan (The Departed). Production is currently under way at Robert Rodriguez's Troublemaker Studios in Austin, Texas.
