After four days of shooting, production on the final season of Fox’s cult sci-fi drama Fringe has been shut down  for two weeks so co-star John Noble can get treatment for a sleep disorder. Filming on the final 13 episodes of the Warner Bros. TV-produced series began last Wednesday with Noble. On Monday, Noble was MIA at the show’s TCA panel when producers explained that he was not feeling well. The series resumed production yesterday without Noble, and a decision was made later in the day to go on hiatus while the 63-year-old actor receives treatment. Word is that Noble has had the condition, first reported by TMZ, for awhile. It was aggravated by his recent intense schedule that had him flying back from his native Australia right into Comic-Con then right into production on Season 5 of Fringe. Filming is now slated to resume on Aug. 7. The delay won’t affect the show’s Sept. 28 final season premiere.
