Colin Farrell told an Irish newspaper he's in the show.

"Three police officers and a career criminal must navigate a web of conspiracy in the aftermath of a murder," is how HBO's press release described the story.

Farrell will play Ray Velcoro, "a compromised detective whose allegiances are torn between his masters in a corrupt police department and the mobster who owns him," and Vaughn will star as Frank Semyon, "a career criminal in danger of losing his empire when his move into legitimate enterprise is upended by the murder of a business partner."
