Oscar-Winning Writer Heads to Second ‘Sin City’

Robert Rodriguez and Frank Miller are bringing in some Oscar-winning firepower to help shape the script for Sin City 2, the sequel to their 2005 hit graphic novel adaptation, reports THR.

William Monahan, who won the Oscar for best adapted screenplay for 2006′s The Departed, has been hired to work on the script, according to sources, supplementing a draft completed recently by Miller.

Momentum has been building lately behind the long-in-development sequel to Sin City, which grossed a healthy $100 million worldwide in 2005. Rodriguez, who co-directed the original with Miller (who scripted and authored the source material), said at Comic-Con in July that financing for the sequel had been arranged and shooting would begin as soon as a script could be locked, possibly by the end of this year.

Many names have been rumored to return, although nothing has been officially announced.
