NBC has cast the lead in their drama/mystery pilot, Midnight Sun. Julia Stiles will play FBI cult specialist, Leah Kafka, as she leads an investigation into the disappearance of Midnight Sun, a cult-like, communal group living in Alaska. Stiles is joined by Emma Bell (Frozen) who plays Rory, the daughter of the cult’s leader (played by Titus Welliver of Lost). Daniella Pineda (Newlyweds) is also on board. From Deadline, the pilot, written by Lisa Zwerling (Awake), is the first series for Stiles, who has previously done a season-long guest starring arc on Showtime’s Dexter.
