Question: Why did Chris Noth leave Law & Order: Criminal Intent? I know he's gone, but what happened?
Answer: According to Law & Order kingpin Dick Wolf in a recent USA Today article, Noth had expressed "frustration as an actor" on the show, as he had during his time on the original series. As Wolf explained: "A lot of actors get frustrated, and I can understand why. One of Jerry Orbach's phrases was, 'Dick, can't somebody die in my arms so I can get an Emmy nomination?'" Sometimes on these shows, the producers oust characters and actors for creative reasons, to shake the show up. Sometimes the actor wants to move on. In this case, it appears to have been something of a mutual decision, and maybe Noth saw an opportunity to explore new pastures given how much higher his profile was likely to become with the release of the Sex and the City movie.
