Hope for U.S. distribution of Joel Surnow's 8-part miniseries The Kennedys is fast fading away. Showtime has just passed on the project, which was cancelled by its original network, History, on Friday. Showtime was considered The Kennedy's best shot for an airing on a traditional network in the U.S. because of 24 co-creator Surnow's long-standing relationship with Showtime's new programming chief David Nevins, who previously ran 24 producing company Imagine TV.
