In the film 'Sin City', who plays Det. Jack "Jackie Boy" Rafferty?

Sin City (also known as Frank Miller's Sin City) is a 2005 American neo-noir crime anthology film written, produced, and directed by Robert Rodriguez and Frank Miller. It is based on Miller's graphic novel of the same name.

Much of the film is based on the first, third, and fourth books in Miller's original comic series. The Hard Goodbye is about a man who embarks on a brutal rampage in search of his one-time sweetheart's killer, killing anyone, even the police, that gets in his way of finding and killing her murderer. The Big Fat Kill focuses on an everyman getting caught in a street war between a group of prostitutes and a group of mercenaries, the police and the mob. That Yellow Bastard follows an aging police officer who protects a young woman from a grotesquely disfigured serial killer.

Det. Jack "Jackie Boy" Rafferty, is Shellie's abusive former boyfriend. Miho kills him and his four buddies after they threaten Becky with a gun. His spirit later haunts Dwight's imagination, and his murder is what precipitates 'the big fat kill' of the title. Despite his blatant alcoholism and abusive behavior towards women, Rafferty is a well-respected hero cop, having ascended to the ranks of Lieutenant. He was given the moniker "Iron Jack" by the newspapers. Portrayed by Benicio del Toro in the film adaptation.
