Nixon will play the Julie Taymor-esque director Amanda Reese, who's attempting to helm a troubled theatrical production called Icarus, presumably based on the Greek myth. In the episode, a botched stunt will result in a death and Reese's spiraling.

Law & Order: Criminal Intent's 10th season will bow May 1 (8/7c) on USA.
