Scott Speedman is making the move from Grey's Anatomy's Seattle to RJ Decker's South Florida - but where is his show actually filmed? Based on Carl Hiaasen's novel Double Whammy, RJ Decker, focuses on a disgraced newspaper photographer and ex-con who "starts over as a private investigator in the colorful-if-crime-filled world of South Florida, tackling cases that range from slightly odd to outright bizarre, with the help of his journalist ex, her police detective wife and a shadowy new benefactor - a woman from his past who could be his greatest ally ... or his one-way ticket back to prison.
