"Book 'em, Danno. Murder one."Hawaii Five-O is a detective show set in Hawai'i, centered on the fictitious "Five-O" elite state police unit (a reference to Hawaii's status as the 50th state admitted to the United States) led by former Navy officer Steve McGarrett, as played by Jack Lord.Running from 1968 to 1980, this show is synonymous with Hawaii, and its iconic theme song (which became a hit single for The Ventures) is regularly played by the University of Hawaii marching band at home games for Hawaii sports teams. Appropriately, the overwhelming majority of the show was shot on location in Hawaii, only occasionally using studios in Los Angeles or other locations as called by episode plots. The show is currently available via various broadcast stations on syndication, on DVD, or streaming from CBS' website.A pilot for a prospective revival series (produced by Stephen J. Cannell and starring Gary Busey, with James MacArthur's Danny appearing as the new Governor) was produced in 1997 but never aired. A completely re-imagined series, titled Hawaii Five-0 (with a zero, not an "O"), debuted in 2010.
— Steve McGarrett
- Absentee Actor: James MacArthur, Zulu and Kam Fong are all absent from "Once Upon A Time, Part II" (which is set entirely on the mainland); the latter two are also missing from "The Ninety-Second War, Part II" and Zulu is further gone from "Good Night, Baby, Time To Die!" Jack Lord did not miss a single episode in the entire run.
- Affably Evil: Wo Fat, and to a lesser extent—in that he's more affable than evil—Lewis Avery Filer. The former moved to Faux Affably Evil from the season nine premiere onward.
- And Starring: Everyone other than Jack Lord. Seriously. The opening credits for the first few seasons: "Starring Jack Lord" (from season six onwards he had this billing on the end credits as well) "With James MacArthur as Dan Williams; Zulu as Kono; Kam Fong as Chin Ho." This was maintained, with adjustments for cast changes, for the entire run.
- And This Is For...: "Bomb, Bomb, Who's Got the Bomb?"
- Artistic License – Biology: "A Bullet for El Diablo" has a dictator's daughter substituted by her twin half-sister. Even Stephen Hawking couldn't calculate the odds on that.
- Belly Dancer: Whenever a hula dancer appears, although this is usually limited to the opening credits.
- Big, Screwed-Up Family: "One Big Happy Family". The daughter is the most sensitive and the only real innocent (she steals a telephone book cover, while the others go for money) whereas the father and son are murderers, the daughter-in-law is a Ms. Fanservice who uses her powers for evil, and the mother (and leader) is a heartless racist who in the denouement says they only kill people who aren't family... and only rob the people they kill because their victims won't be using the money. Writer Alvin Sapinsley based this on a real family, yet!
- Book Ends: "Up Tight" starts with Danny trying to keep a young woman high on LSD from jumping off a cliff, and ends with McGarrett trying to keep the professor who turned her onto drugs from jumping off the same cliff. The woman jumps, but the man is rescued and arrested.
- California Doubling: Averted big time, and one of the first American TV shows to do so. That's part of what made this show very famous.
- The two-parter "Once Upon a Time" was almost entirely shot in California because it was almost entirely set there. These episodes were among the few not to carry the "Filmed entirely on location in Hawaii" credit.
- The feature-length episodes "Nine Dragons" and "The Year Of The Horse," with scenes in Hong Kong and Singapore respectively, were indeed filmed there.
- Played straight in one episode that had scenes set in the Philippines... which were more likely shot in Hawaii. Though considering the superficial similarities and how many Filipinos were in Hawaii even during the time the series first aired, it's partially justified.
- Catch Phrase: "Book 'em, Danno."
- The Chessmaster: The team frequently maneuver baddies into confessions by insanely complex plots, anticipate traps and seem to walk into them, only to reveal backups (and tape recorders) in place right when the baddies inevitably tell all before shooting, etc. Example, Season 4 "Good Night Baby, Time To Die!": a woman who is frightened because her framed boyfriend is said to be escaped from prison and coming for her, so she starts confessing to crimes (the framed prisoner is not really loose; he's doing it all under Five-O supervision in order to be absolved.) Bad guys sometimes seem like Chessmasters, but of course *their* insanely complex plots always come a cropper after baffling the team for about 40 minutes. Sort of exception: although Wo Fat's scheme in "The Ninety-Second War, Part II" is counteracted, it's done so in a way that he thinks it worked.
- Chuck Cunningham Syndrome: Kono and Danno. Sadly averted with Chin Ho.
- Creator Cameo: Theme song composer Morton Stevens played a jazz drummer in the third season episode "Trouble in Mind".
- A Day in the Limelight: Dan Williams takes charge in "For a Million... Why Not?" and "Charter for Death" when McGarrett is sidelined by a trial and quarantine respectively (although he still appears in both episodes). "Cry, Lie," meanwhile, is a rare episode to focus on Chin Ho.
- Destination Defenestration: "I'll Kill 'Em Again" and "Stringer."
- Driven to Suicide: "Up Tight," "To Kill or Be Killed," "Death With Father," "Is This Any Way To Run A Paradise?", "I'll Kill 'Em Again."
- Downer Ending:
- In "To Kill or Be Killed", a soldier on leave from The Vietnam War falls to his death, and his brother (suspected of being involved) is bidding to avoid the draft and flee to "Trudeau turf" (alias Canada) because while he's willing to fight he doesn't believe this particular war is justified, to the disgust of his father — a military man. It turns out that the soldier committed suicide because he couldn't face returning to what he also felt was an unjust war; not only is the would-be draft-dodger caught, but his father disowns him by saying "Then I have two dead sons."
- "Three Dead Cows at Makapuu, Part II" has a scientist aiming to release some shortlived but very deadly bacteria to protest chemical warfare being persuaded (partly due to a telephone operator who falls in love with him) not to do so, but the vial he stole is taken... and cracked. He manages to control the spread of the germ, and the vial is incinerated along with the shack where it was kept, but he himself is infected and succumbs as McGarrett and the woman he loves watch.
- Dying Moment of Awesome: Chin Ho, after being revealed as a Five-O plant, immediately slugs the leader in the face and then attacks the other two thugs. While he's ultimately unsuccessful at trying to escape, and the leader mocks him at what he did being a mistake, he replies that it was worth it and he doesn't think he has much left to lose. Sadly, he's right.
- External Combustion: "Blind Tiger". It temporarily blinded McGarrett.
- Fan Disservice: "The Box" opens with a shower scene in prison. Not so bad you say? Big Chicken's taking the shower.
- Fanfare: The iconic theme music.
- Fanservice: It's a show set in Hawaii. What do you think? (Not to the extent of the new show, mind you.)
- Final Season Casting: While Zulu (the original Kono) left the show in 1972, James MacArthur and Kam Fong hung around until 1979, with William Smith (as Kimo), Sharon Farrell (as Lori) and Moe Keale (as Truck) as the new regulars.
- Forensic Drama: It wasn't primarily this, but Che Fong showed up an awful lot.
- Forgotten Theme Tune Lyrics: The song has lyrics.
- If you're feeling lonely
You can come with me
Feel my arms around you
Lay beside the sea
We will think of something to do
Do it 'til it's perfect for you
And for me too
You can come with me!
- Getting Crap Past the Radar: In "Tricks Are Not Treats", the writers apparently weren't allowed to refer to the pimps as pimps, but managed to work in Lolo's nickname for them: "pimples".
- Hidden Depths: Of all people, Wo Fat in "And a Time to Die...". It's heavily implied that he lost his family long ago during uprisings in China, and he really didn't want to kill the girl he'd taken hostage, of whom he was surprisingly kind and forward with. The problem was, according to him, is that to be taken seriously on both sides he had to live up to his word, so he would have had her killed if her father didn't do as he'd asked. That was the only episode that showed Wo Fat as still someone human and not a Card-Carrying Villain.
- Hoist by His Own Petard: In "Nine, Ten, You're Dead," a former boxer shatters the hand of a novice to keep him from ruining his health and life, causing the mobster backing the young boxer to put out a hit on the older man. A hitman arrives... and takes out the mobster, as his bosses felt he was out of control. The former boxer is left unharmed, because the hitman assures him he doesn't kill anyone without getting paid for it.
- Hook Hand: The villain in "Hookman", as played by real-life double-amputee J. J. Armes.
- Infant Immortality:
- Averted in "The Listener," in which a psychiatrist is targeted by a man who's bugged not only his home but his office — the villain averts Even Evil Has Standards by among other things playing a young boy a taped conversation between the doctor and the boy's mother, where she reveals he has a fatal brain tumour. The doctor tells the boy the tumour is shrinking... and later tells McGarrett that the boy really is dying.
- Also averted in the two-parter "Once Upon a Time", where McGarrett's sister is in thrall to a quack doctor who claims she can cure her baby, who has cancer. The child passes away long before the end of part one.
- It's Personal: "Once Upon a Time", in which McGarrett is determined to take down fraudulent doctor C.L. Fremont after what happened to his sister's child.
- Joker Jury
- Killed Off for Real: Chin Ho.
- Large and in Charge: Big Chicken, played by pre-WJM/pre-Pacific Princess Gavin MacLeod.
- Long Runner: Let's put it this way, Hawaii Five-O is the only scripted, prime-time U.S. series to have debuted during the 1960s and made it all the way to the 1980s.
- Made of Iron: McGarrett. As the series went on the script writers actually had some fun with Lampshade Hanging. One episode has a would-be killer fire at McGarrett several times with no effect until she screams, "What are you made of!?" McGarrett's response? It's not him but the bullets, which were blanks.
- Manchurian Agent: Wo Fat's spy ring makes use of them in "A Bullet for McGarrett".
- Master of Disguise: Lewis Avery Filer.
- Not So Different: The whole point of the 1969 episode "Not That Much Different".
- Omniscient Database: An early example, possibly the first for cop shows. The Honolulu Police Department computer was frequently called upon for information, sometimes for things that in real life weren't available in digital format until the 1990s or later.
- Ooh, Me Accent's Slipping: Albert Paulsen's Ecuadorian accent shows up quite a bit as gangster Edmonds in "Nine, Ten - You're Dead."
- Pilot Movie: While the pilot movie has the same name as the series, it runs in two parts in syndication as ''Cocoon" (with the standard opening title sequence changed to remove the shot of James MacArthur, as he didn't play Dan in the pilot).
- Pre-Mortem One-Liner: A hitman disguised as a doctor to his hospitalised target in "Death with Father":Hitman: Time for your shot.
Patient: What shot?
Hitman: This one. (kills him with a silencer-equipped gun)
- Reality Is Unrealistic: Five-O is supposed to be an elite unit of the Hawaii State Police. The closest thing Hawaii has to a state police is the Sheriffs Division within the State Department of Public Safety, and they're limited to specific duties such as acting as process servers and providing security at state facilities.
- Rogues Gallery: Wo Fat; Tony Alika; Honore Vashon; Lewis Avery Filer; Big Chicken.
- Scenery Porn: Yes.
- Sequel Episode:
- "The Bomber And Mrs. Moroney" features the brother of the boy Danno seemed to have killed in "...And They Painted Daisies On His Coffin," seeking revenge. He didn't do it.
- "The Case Against McGarrett" picks up where the three-parter "V For Vashon" left off, with Honore Vashon and other convicts putting Steve on trial.
- Serial Killer: "One for the Money", "I'll Kill 'Em Again", "Wednesday, Ladies Free" and others.
- The Smurfette Principle: Lori Wilson is the only female regular in all twelve seasons... and she didn't arrive until the final season (and only appeared in ten episodes at that, disappearing before the Series Finale "Woe To Wo Fat").
- Spell My Name with an "S": In the end credits for "Face of the Dragon," guest star Nancy Kovack is billed as Nancy Kovak.
- Split Personality: In "Bomb, Bomb, Who's Got The Bomb?", a senator is being terrorized by a bomber. Unknowingly, he's the bomber - because he accidentally shot and killed his own father as a boy and has never forgiven himself.
- Suspiciously Similar Substitute: Monsieur Bordeaux in "30,000 Rooms and I Have the Key" for Lewis Avery Filer. Both characters came from the same writer, and the three episodes — Mr. Filer was in "Over Fifty? Steal" and "Odd Man In" — even share music ("Over Fifty? Steal" has an original score by Morton Stevens, the other two have tracked music).
- Syndication Title: McGarrett
- Taking You with Me: "Death with Father."
- The Teaser
- Television Geography: Mostly subverted, since most of the series was filmed on location in Hawaii, and locations were rarely specific enough to reveal obvious mistakes to most viewers.
- Temporary Blindness: McGarrett in "Blind Tiger", when an assassination attempt failed to kill him.
- Title Drop: "Strangers In Our Own Land," "One for the Money," "Just Lucky, I Guess," "A Bullet for McGarrett" and "Why Wait Till Uncle Kevin Dies?" all work their respective episode titles into the dialogue.
- The Vietnam War: Many of the early season episodes revolved around the war, ranging from naval personnel smuggling drugs out of Southeast Asia, screwed-up veterans committing (or being victims of) crime, to con men taking advantage of military personnel on leave.
- Title Sequence:
- The opening titles are legendary.
- The canoe-paddling end credits bit (introduced in Season 2; the first season has a flashing police light) is also very well known.
- What Happened to the Mouse?: The 2-hour pilot, Cocoon, has Nancy Kwan playing Rosemary Quong, a mildly hippie grad student with a penchant for miniskirts. Kwan gets second billing in the opening titles, right after Jack Lord, and they have several scenes together, including a beachfront cookout, playing up the contrast between the free-spirited Rosemary and the buttoned-down straight-laced McGarrett. The ending suggests that Rosemary is going to be McGarrett's recurring love interest. She's never seen again.
- Yellow Peril: McGarrett's Chinese nemesis, Wo Fat.
McGarrett: (to the villains at the end of "3,000 Crooked Miles to Honolulu") Aloha. Aloha, suckers!
