Didn't We Meet at a Murder? - S4-E22

Character mistake: When Chin Ho reads Wellman's license plate number to the police dispatcher and repeats it to confirm, he recites a different number the second time. (00:30:05)

Jean G

Cloth of Gold - S4-E20

Revealing mistake: Near the end, McGarrett's boat is preceded by the wake of another boat that isn't there when the angle of the shot reverses. The wake belongs to the vessel carrying the camera crew. (00:46:45)

Cloth of Gold - S4-E20

Revealing mistake: When the underwater camera breaks the surface in what is supposed to be open ocean, the domed roof of a Hawaiian aquatic theme park building is visible in the background.

While You're at It, Bring in the Moon - S4-E19

Continuity mistake: McGarrett approaches the Governor's office building wearing a light blue suit, but enters the lobby wearing a dark navy blue one. (00:27:05)

Jean G

Skinhead - S4-E18

Continuity mistake: McGarrett leaves the parking lot driving a two-door Ford Mercury, but arrives at the crime scene in a newer, four-door model. (00:07:25)

Jean G

The Ninety-Second War (2) - S4-E17

Continuity mistake: When Vogler stands in the doorway talking to Danno, the position of his arms alternates with each change of shot, from down at his sides to propped at 90-degree angles on his hips. (00:42:05)

Jean G

The Ninety-Second War (1) - S4-E16

Factual error: An injured McGarrett is trapped in an overturned car, which emergency workers flip over before cutting him free. No rescue crew would ever do this: such violent movement could kill the patient. It's crucial that crash victims be extricated without causing further trauma: McGarrett would be freed leaving the wreck exactly where it was - upside down. (00:07:25)

Jean G

Odd Man In - S4-E14

Continuity mistake: At the end, Filer puts his jacket on, and the left side of his shirt collar is sticking out above the coat. Every time the camera angle changes, though, the shirt collar is neatly tucked in. (00:49:00)

Jean G

A Matter of Mutual Concern - S4-E11

Visible crew/equipment: As the mob bosses gather for their summit meeting, one of their big black Lincoln Continentals reflects several banks of studio lights when it comes through the security gates. (00:16:40)

Jean G

Rest In Peace, Somebody - S4-E10

Character mistake: Cameron's attempt to assassinate the governor fails because McGarrett has everyone wear bullet-proof vests. It's been established that Cameron is brilliant, a top-of-his-class ex-cop and a crack shot. And he's been sending death threats, so he knows they'll expect him. Yet he fires at the governor's back and is shocked that the man doesn't die. Anyone with his expertise would have anticipated the vests, and aimed for the man's head. (00:48:20)

Air Cargo -- Dial for Murder - S4-E7

Visible crew/equipment: The crooks drive off in their blue '56 Chevy, capturing the reflection of a row of studio lights in the car's shiny side panel as it pulls away. (00:34:15)

Jean G

Air Cargo -- Dial for Murder - S4-E7

Visible crew/equipment: When the bad guys enter the print shop, the boom shadow moves across their heads and onto the wall behind them. (00:11:10)

Jean G

Air Cargo -- Dial for Murder - S4-E7

Visible crew/equipment: In the office, when McGarrett hands Chin Ho the murdered cop's notebook, the microphone shadow can be seen moving across the set wall at the upper left of the screen. (00:14:15)

3,000 Crooked Miles To Honolulu - S4-E4

Audio problem: During McGarrett's second visit to question the professor, in the midst of their conversation, something off-camera makes a very loud thump. Professionals that they are, Buddy Ebsen and Jack Lord carry on with their lines as though nothing has happened. But this looks just a bit odd, because you wonder why their characters aren't curious about the noise. (00:34:10)

Jean G

3,000 Crooked Miles To Honolulu - S4-E4

Factual error: The professional hitmen murder their victim in the hospital with a silenced .38 revolver. You'd think the mob would know better. Silencers have absolutely no effect on revolvers. They only work on closed-chambered, automatic weapons. (00:46:20)

Jean G

No Bottles...No Cans...No People - S4-E2

Factual error: Johnny makes two direct-dial calls from his car phone and is instantly connected - something not yet possible in 1971. His calls would have to go through a mobile operator before connecting. (00:32:30)

Jean G

Highest Castle, Deepest Grave - S4-E1

Revealing mistake: Stock footage turns the doctor's black 1970 Lincoln Continental into a 1950s model when it goes over the cliff, crashes and burns. (00:15:50)

Trivia: Throughout the first two seasons, both McGarrett and Danno often referred to "Chief Dann of HPD." This was a thank-you to CBS programming chief Mike Dann, who helped first persuade the network to put Hawaii Five-0 on the air, and also got it a better time slot later on.

Trivia: Though he somehow remained in office for all 12 years of Hawaii Five-0's run, the Governor never had a name until episode 208, when he was referred to as "Governor Paul Jameson." Most TV trivia sources wrongly insist that his name is Philip Grey - but this was another character played by the same actor (Richard Denning) in episode 6, "The 24-Karat Kill," before he was permanently cast as the Governor.

Season 1 generally

Trivia: Five-0's film crew once helped the real HPD with a real-life arrest. Ten genuine cops, working crowd control during the filming of an episode, took a break from their guard duties and went into a nearby warehouse. They emerged with several gambling-ring suspects in handcuffs. The police lieutenant explained to the bewildered film crew, "Until today, we couldn't get near this place without tipping these guys off. Thanks for the great front!" The crooks had assumed that all the cops were actors, so hadn't given them a second thought.
