Are Hawaii Five-O and Magnum P.I. in the same universe?

Hawaii Five-O and Magnum PI

Growing up I watched a lot of Hawaii Five-O and I watched a lot of Magnum P.I. Yet, despite them both being Hawaii-based shows, it didn’t once occur to me that the shows might operate within the same universe.

Imagine my surprise when I spotted something that stated that they obviously were. Obviously? Digging deeper, I found the Poobala website and a page detailing just how close the shows were. In a late episode called Skin Deep, Magnum contacts a helicopter tower and, pretending to be from the police, utters “Billy, this is McGarrett of Five-Oh. Is David Norman armed?”.

So, either this was Magnum pretending to be a fictional character from a TV show (!), or in the Magnum universe, there was an officer called McGarrett working for the Five-O. Apparently Magnum referred to the Five-O often throughout the series so it is plausible that the shows were meant to co-exist? After all, Magnum also crossed over into the world of Jessica Fletcher from Murder, She Wrote too!

And what of the Hawaii Five-O remake? Well, the video above is a nice little nod to it’s history with Magnum, don’t you think?

    Don’t forget that Simon & Simon were in the same world as Magnum P.I.

    Magnum P.I. was originally envisioned as a continuation of Tom Selleck’s character on The Rockford Files, but fortunately that changed.

    I did a quick check to see if either Magnum, P.I. or Hawaii 5-0 were a part of the Tommy Westphall universeā€¦as far as I can see, they’re not. So that’s something.

  3. TheSixMillionDollarJedi says:

    It’s too bad the new Hawaii Five-O referenced Magnum as a TV series rather than an actual person in that universe. That could have opened the door for Tom Selleck to guest star.

  4. The links go further. In real life, Magnum was created, in part, to take advantage of the Hawaiian production facilities and resources that were going to be left unused when Hawaii 5-0 went off the air.
