Nightmare in Blue - S6-E21

Continuity mistake: Danno drives away from 5-0 headquarters in a 1972 Ford LTD, but arrives at the crime scene in a '73 with a distinctively different front grill. (00:04:05)

Jean G

The Banzai Pipeline - S6-E16

Visible crew/equipment: When Danno pulls up to the beach house, several light panels are visible, reflected on the surface of his car door.

Jean G

The Finishing Touch - S6-E11

Character mistake: McGarrett mispronounces his old friend Cargill's name in the bank vault scene, giving it a soft G and calling him "Car-jill." Earlier in the episode, and in all the scenes after this, he correctly says "Cargill" with a hard G. (00:17:00)

Jean G

A Bullet for El Diablo - S6-E10

Factual error: Pepe and Carlos are driving a '62 Chevy. When they watch Ramos' motorcade pass, there's an insert shot of a key in the steering column as they start the car. In a 1962 model, the ignition would have been on the dash, not the steering column. (00:13:15)

Jean G

A Bullet for El Diablo - S6-E10

Continuity mistake: When Rita shoots him, Ramos dies face up on the floor, and she flees without touching him again. When McGarrett finds the body, it's lying face down. (00:20:05)

Jean G

A Bullet for El Diablo - S6-E10

Plot hole: During his investigation, Danno learns that the kidnapped Maria never wears make-up. Yet in every single shot we see of her, Maria is far from cosmetics-free. She's wearing very heavy eye make-up. (00:34:40)

Jean G

A Bullet for El Diablo - S6-E10

Trivia: The sleazy, posterior-scratching landlord was played by Charles Dubin, who usually worked behind the cameras. He directed dozens of Hawaii Five-O episodes. (00:42:45)

Jean G

A Bullet for El Diablo - S6-E10

Factual error: Che makes the voice-print comparison using a polygraph machine - a device used for lie detection, not voice analysis. (00:36:30)

Jean G

Little Girl Blue - S5-E20

Revealing mistake: During the bunker siege, footage recycled from an earlier episode creates the sudden appearance of a white station wagon parked beside the police cruisers that isn't there in all the other shots. (00:41:40)

Jean G

Little Girl Blue - S5-E20

Continuity mistake: After murdering the cop, Frank and Luther steal a rifle from the squad car, then close the door. No one goes near the car again, but a few minutes later, the door has re-opened itself. (00:06:00 - 00:11:15)

Jean G

The Capsule Kidnapping - S8-E22

Continuity mistake: During the airport chase, the airplane the bad guys board has propellers. As soon as it's airborne, though, it becomes a jet.

Jean G

The Clock Struck Twelve - S5-E12

Character mistake: After distracting the guards, Danno tosses a grappling hook onto a ledge and climbs the side of the building. He then goes about his business, carelessly leaving the hook and rope dangling from the ledge for all to see. For a seasoned 5-0 team member, that's pretty sloppy covert operations. (00:22:40)

Jean G

The Clock Struck Twelve - S5-E12

Plot hole: As a security test, McGarrett secretly has several dummy bombs planted in the court building, then later shows the governor where they are. Each time he pulls one of the devices from its hiding place, citizens in the courthouse stroll casually by without so much as glancing at the loudly-ticking "bomb." No one knew about the test, so McGarrett's bombs should be attracting some attention, if not causing outright panic. (00:05:00)

Jean G

'V' For Vashon: The Father (2) - S5-E10

Continuity mistake: From his office on the second floor, McGarrett looks out at the office building across the plaza. But the POV shot that follows is taken from ground level.

Jean G

'V' For Vashon: The Father (2) - S5-E10

Character mistake: Hayward tells Vashon that McGarrett's office is on the third floor of the Iolani Palace. Previous episodes have placed the office on the second floor, or have shown the palace to have only two floors. (00:31:45)

Jean G

Journey out of Limbo - S5-E8

Continuity mistake: When the police cruiser with Danno aboard leaves HPD HQ, it's a 1967 Ford Galaxy 500 with wind wings. But in the next shot of it on the Honolulu streets, the car is a '71 or '72 model with no wind wings. (00:43:30)

Jean G

Fools Die Twice - S5-E6

Revealing mistake: A loud, fierce gun battle rages between dozens of 5-0 sharpshooters, Army MPs and the desperadoes inside the payroll office. Amidst all the high-powered rifle fire, a woman in a blue dress strolls casually by in the background, well within bullet range, and never even turns her head to see what all the ruckus is about. Gee, you'd think colossal shooting wars broke out on her block every day. (00:13:30)

Jean G

You Don't Have To Kill To Get Rich -- But It Helps. - S5-E3

Revealing mistake: We see the body of Karen Bell 30 fathoms underwater, with her feet tied to a concrete block. But just before the shot cuts, the "corpse" wiggles its toes.

Jean G

Death Wish on Tantalus Mountain - S5-E2

Character mistake: McGarrett tells Pereno that the sabotaged race car went over a cliff. But the car crashed into a wall, with no cliff in sight. It's very unlike Hawaii's top cop to get the facts wrong - especially when he was an eye witness to the event. (00:44:00)

Jean G

Death Wish on Tantalus Mountain - S5-E2

Visible crew/equipment: On top of the mountain, miles from any artificial light source, several studio lights and reflector panels are visible in the side of McGarrett's shiny black Mercury. (00:14:45)
