Inception

NBC picked up four additional pilots Thursday, including three comedies and an Inception-style thriller that explores dual realities.

REM, a twist on the typical crime procedural, centers on a police detective who's involved in a traumatic car accident and then wakes up in two fractured realities. The project follows his simultaneous and parallel lives with his broken family. As the title suggests, the Rapid Eye Movement sleeping state may have something to do with the cop's split perceptions. Warner Bros.' Oscar-nominated film Inception played with the idea of manipulating and controlling one's dream state.

REM is from Kyle Killen, creator of Fox's short-lived Lone Star, which was also about a man who lived two lives albeit in reality with two separate families.
