When did the Hawaii Five-O movie premiere on TV?
A week before the series, on September 20, 1968 It should be noted that either of these dates, as well as any of the air dates of any other of the episodes during the 12-year run of the show, may vary from these “official” dates (the CBS network airdates) in any particular local market because of pre-emption or other schedule shifting on a local level. Episode guides do not take these local shifts into account; that would be impossible to track down and too space-consuming to include.
