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.

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.

Continuity: Pool balls redistributed on pool table between the time after the Sargeant breaks and McGarrett casually takes a shot. Especially, noticeable since Tommy, the other player, does not move off the table's edge after the break when two balls comes towards his position and his bottom or pants may interfere with their travel. In the next shot involving the table, those balls are not there and the rest of them seem more evenly distributed across the table.

Continuity: When Nagata breaks into the boarded-up house, he walks through a doorway full of cobwebs, covering his black suit with white dust and webs. But when the shot changes, his suit is suddenly perfectly clean again.

Visible crew/equipment: When Wo Fat's lackey drives away from the Chinese pharmacy, his car door reflects the camera crew and set lights.

Revealing: McGarrett and Victoria watch surfers from the beach. Thanks to the insertion of stock footage, they "see" surfers riding huge 6-foot waves. But in the shots of the actual locale behind them, the ocean is virtually flat.

Visible crew/equipment: At the end, when McGarrett walks around his desk to confront Sloan, the boom shadow sweeps across the wall at the upper left of the screen.

Continuity: The bad guys are driving a dark green '62 Cadillac - with fins. After Five-O's sharp shooters fire at it, the Caddy hits a concrete wall. In the next shot of the wreck, the green '62 has turned into a black '64 - without fins.

Continuity: When Angela is talking to Sloan, her position in the hotel room chair changes back and forth noticeably between takes.

Deliberate "mistake": Han is shot several times as he dives from the board into the pool. But when his body is shown slowly floating back to the surface, there's not a trace of blood on him or in the water.

Continuity: As Kono talks to Johnny Kalama in the students' apartment, an orange lava lamp sits on the shelf between them. Each time the camera angle reverses, the wax bubbles in the lamp are very noticeably in different positions and configurations.

Continuity: Danno, posing as a photographer on the beach, snaps the shutter at a bikini-clad girl and quips, "I only wish I had some film." Seconds later, he takes a picture of the suspects that's then used to identify them. The scene is continuous, and at no time did he ever load film into the empty camera, nor did he have another one.

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

Audio problem: When McGarrett and Danno pull away from the curb in McGarrett's big black Mercury, the tire-squealing sound effect begins before the car actually starts to move. (Doesn't happen unless you're flooring it and "peeling out," which they're not.)

Continuity: Although the plane making an emergency landing is repeatedly referred to as a jet, the aircraft we see in the air (and later landing) is a prop job.

Factual error: Don, who professes to be a Buddhist, chants in the jail cell and refers to Buddha as "god." Adherents to this religion do not worship the Buddha and never refer to him as god. Later on, Don chants to Krishna, a Hindu deity not even remotely connected with Buddhism. So, just what is Don - a Buddhist or a Krishna?

Factual error: Tommy races past the outside of two of Five-O's office windows before climbing in through a third. Unless he can fly, this is impossible: McGarrett's office is on the second floor, and its windows have balconies that are not connected to each other.

Continuity: Danno drives to Brohme's house in a black 1966 Ford Galaxy 500, but arrives in a green 1969 Ford LTD.

Continuity: Recycled footage is again a bit too obvious here, when McGarrett's 4-door Mercury suddenly becomes the 2-door model he drove in the pilot film. It also causes him to arrive, exit the car and walk into the building wearing a grey suit, but enter the Federal agent's office in the next shot wearing a blue suit.

Continuity: At the end, Krenter is shot during the final gun battle on the beach. Between takes, his body and the deflated rubber raft that was also on the sand both disappear.
