Bad Chi - S2-E9

Factual error: Darien sets up a tripod and videotapes himself leaving a message for the Agency. When the tape is played back later, the camera can be seen to have both zoomed in and panned to follow his movements, even though no one was there to make those adjustments. (00:30:30)

Jean G

Factual error: When Richard Collier first arrives in 1912, the woman getting dressed in the hotel room is humming "You Made Me Love You," a song not published until 1913. It was first recorded by Al Jolson in June of 1913. The lady in the hotel shouldn't have known it yet. (00:30:00)

Jean G

The Invisibles - S1-E19

Factual error: The General brandishes a six-shooter pistol with an enormous silencer attached to it. He's a career military guy who should definitely know better, so he gets a failing grade in Basic Weaponry 101. Silencers don't work on revolvers. (00:34:50)

A Thousand Pardons -- You're Dead! - S2-E1

Factual error: Danno, who's posing as a Marine, has hair that's far too long to be permitted in the Corps. In fact, all of the Marines in this episode have non-regulation (too long) haircuts. 'T'was the same then as it is now: US Marines are given "buzz jobs," and hair longer than an inch is not allowed.

A Thousand Pardons -- You're Dead! - S2-E1

Factual error: At the end, Simms shoots at McGarrett and is instantly riddled with bullets from the 8 or 9 cops who shoot back. Yet, when McGarrett walks over to the body, there are no holes - and no blood - marring Simms' pristine uniform. (00:48:00)

Season 10 generally

Factual error: 10-13 "The Big Aloha": McGarrett compliments Palahana on his surfing skills with the line, "Nice ride." But the ocean behind them in the shot is virtually flat. With no waves, Palahana's supposed "nice ride" is impossible.

Jean G

Season 10 generally

Factual error: 10-4 "The Friends of Joey Kalima": Guest star John Rubinstein (son of classical pianist Artur Rubinstein) guest stars as Joey - but his name is misspelled in the end credits as "Rubenstein."

Not That Much Different - S1-E23

Factual error: In the final shootout scene at the end, Manning's .38 caliber 6-shooter pistol fires 8 successive shots at McGarrett without being reloaded. (00:45:00)

Jean G

Season 8 generally

Factual error: 8-12 "Honor is an Unmarked Grave": Marshall has been in Hawaii for only 3 weeks, yet he has his cat, which he brought along, living with him. Hawaii requires a 4-month quarantine on all pets brought in from the mainland. Marshall's kitty should still be in lock-up.

Jean G

Birds of a Feather - S1-E1

Factual error: Talking to Dresden, Bob refers to his first grimoire (a book of spells & magic). But the closed captioner, apparently unfamiliar with the term, has rendered the line, "My first Renoir," which, though amusing, makes no sense at all in the context of the conversation. (Refers to the aired version: the error was corrected on the DVD release.) (00:24:00)

Jean G

The Singapore File - S2-E9

Factual error: During the shoot-out at the end, McGarrett's 6-chamber .38 caliber police special fires 8 rounds without being reloaded.

Jean G

The Jinn Who Clears The Way - S5-E5

Factual error: Danno, who's been a cop long enough to know better, reports to McGarrett that the lab has determined Wong's blood type to be AO. Blood is typed as A, B, AB or O. There is no type AO.

Jean G

It Crawled Out of the Woodwork - S1-E11

Factual error: When the energy monster kills his entire research staff by stopping their hearts, Dr. Block brings them all back to life (with their minds and personalities intact) by installing pacemakers. But when the heart stops functioning, brain death occurs within minutes. For this to work, he'd not only have to operate on several people simultaneously, he'd also have to be the fastest heart surgeon on Earth. (00:40:00)

Jean G

Factual error: In 1912, Richard Collier gives young Arthur his ball, and above their heads, you can see the 1980 fire sprinklers in the ceiling. (00:40:40)

Jean G

Factual error: The 1912 hotel has frosted light bulbs hanging from the ceiling in some scenes. Frosted bulbs weren't around until the 1940s. (00:43:15)

Jean G

The Face of the Dragon - S1-E17

Factual error: Two deaths by bubonic plague, spread by casual human contact, have Five-O scrambling to prevent an epidemic on Oahu. But the disease isn't spread this way (its vector is fleas on infected rats). And since the introduction of antibiotics in the 1940s, bubonic plague has been imminently curable, so there was no need for panic, other than, of course, to make the episode more dramatic. (00:18:00)

Jean G

The Incredible World of Horace Ford - S4-E15

Factual error: In the opening scene, Horace painstakingly loads his six-shooter cap pistol with a six-cap round - then shoots his boss with it seven times. (00:00:40)

Jean G

To Lure a Man - S3-E13

Factual error: Mundy makes a phone call by wiring a radio speaker to the wall jack. Clever, but it wouldn't work. He might be able to hear dial tone, etc., but no one he called would be able to hear him without a microphone/sound pick-up, which the radio didn't have. (00:16:15)

Jean G

Chase Through Time - S1-E24

Factual error: Doug and Tony time travel to one million years B.C., where they encounter dinosaurs. Not likely. All the dinosaurs were rendered extinct several million years earlier by an asteroid strike. There weren't any left by 1-million BC. (00:29:45)

Jean G

Visitors From Beyond the Stars - S1-E18

Factual error: The aliens show Doug and Tony the planet they plan to invade - Earth, of course. But the special effects department forgot to give poor old Earth any clouds. (There are clouds over more than 70% of our planet at any given time.) When they go down to the surface, though, there are plenty of clouds in the sky. (00:05:20)
