Michael C. Hall (Dexter) is sticking with Showtime, though it will be in a primarily behind-the-scenes role.  Hall will take on the title of executive producer for a new series based on the Matthew Specktor novel, American Dream Machine.  Set in Hollywood but fluctuating between the 1970s and modern times, the story centers on talent agents and their troubled sons.  If the project moves forward to pilot, Hall may be eyeing a small role but will focus mostly on his off-camera duties.  Dexter showrunner Scott Buck will supervise the script, also written by Specktor.  Hit the jump for more.

THR reports that Hall will serve as executive producer on the American Dream Machine series for Showtime.  Meanwhile, Hall will be wrapping up the bloody serial killer series Dexter with its final season that kicks off June 30th.
