Goofs

In the morgue scene, Summer can be seen first wearing doctor's coat , then removing it, then coat it's on again, whenever the camera cuts back to her or her reflection.

When Mitch throws the bad guy off balcony with a pail on his head, you can see it falling off as he falls. But when he lands in the water it is back firmly on the bad guys head again.

After the gauntlet Mitch and the others run off to save someone drowning. Brody runs after them and 'commandeers' a bike. He is shirtless. Next image is Brody overtaking CJ an Stephany on the bike wearing his tshirt.

When Mitch is talking to Brodie after being selected as a trainee, the camera goes back and forth to get either of the actors reaction. When focused on Dwayne, Zac's hair is messy. When focusing on Zac, Zac's hair is gelled back.

At the end of the movie when they are sitting on the patio several shots show a man sitting in a folding chair. He then disappears and reappears between camera angle changes.

They mention a scenario of manta rays flying out of the water stinging people in the chest and subsequently make a joke about Steve Irwin's death. Manta rays are completely harmless and don't have hard, pointed barbs; stingrays do and Steve Irwin was killed by a stingray, not a manta ray.

When hiding in the hospital morgue drawers, Mitch states that formaldehyde melts fat and the liquefied fat was dripping on Brody's face. However the bodies in hospital morgues are only refrigerated before autopsies are done, never embalmed, so there would not be any formaldehyde in the tissues. Embalming would only be done later at a funeral home.

There is no way the drugs in the small plastic bag could have stayed slipped under the party-goer's swimsuit while being thrown in the ocean.

There is ample time to remove Mitch's rash top before piercing it with the needle: it is not sanitary and could trigger complications and an infection.

At the start, there is a camera moveover just before Ronnie is making fun of because of the chesthair. The sign is readable for the camera and therefore reversed for the people it's supposed to be readable for.

The first time he takes off his shirt, Ronnie has a comically strange chest hair pattern. However, for the rest of the film, his chest is completely hairless.

It is very likely that a kind colleague offered to shave or wax it.

When Mitch meets Matt, he has no idea who he is. But later he says he watched Matt on TV when he won his Olympic medals.

It is very possible that either Mitch was lying to him to throw him off or that he watched the Olympics race after meeting him.

The dead councilman is obviously moving and breathing during the close-up shot on his watch.

When the cage with Matt Brody gets to the bottom, there's a scene of the boat sailing away. The scene is reversed, because the navigation lights are on the wrong side of the ship. Red light should be on the port (left) side and green light should be on the starboard (right) side.

The needle used to inject Mitch in the deltoid is too long and would likely have hit the bone.

When on the beach, Mitch's reactions are filmed and the audience can see Brody's head and jaw from the back: he is speaking without moving his jaw.

The opening sequence offers very loud sounds of surfers and a stand up paddler paddling in the water. These sounds are actually very quiet (especially to be effective) and cannot compete with the sound of the waves crashing around. But as always, Hollywood needs to be over the top.

When talking about evidence in the police officer's office, the words "doesn't exist" are seen uttered by Mitch but it is actually Brody's voice (he is finishing his sentence).

Early in the film, when Mitch (Johnson) talks to Matt (Efron) on the beach while he's sitting and drinking, there's a closeup of Mitch's face where a cameraman is reflected on his shades. It's so detailed that the viewer can see the towel under the crew guy and the sea behind him.

At the beginning of the film it shows the sun rising over the ocean. Since it's set in California, the ocean is to the west and they only get sunsets.

When Mitch Buchannon, Mat Brody, and Victoria Leeds pursue the thugs out of the hospital, they almost immediately enter the park and within seconds arrive at the beach. Memorial Hospital is nearly 3 miles southwest of Forsyth Park. Tybee Island is another 18 miles east of Forsyth Park. It would have taken Buchannon and the thugs almost seven hours to run from the hospital to the park and then the beach.

There is no way the lifeguards would not have spotted the clouds of smoke from the nearby boat on fire.

Thorpe states this is the busiest time of the year and yet they are only starting the try-outs to get more recruits to be trained.

There is no way the thugs would not have heard Mitch and Brody argue inside the cubicles at the morgue.

When Summer lifts up her shirt, to distract the guy biking towards her, her bra is white with a blue floral patterns. When the screen cuts back to her, the bra has magically changed. It is clearly a gray bra now.

When Ronnie gets the carrot stuck in his throat and is "choking" (at 11:39), his buddy Dave yells to CJ that Ronnie is choking. Ronnie responds (in a raspy voice), "No, not CJ, Not CJ. No, no!". CJ runs up and says "Are you OK? You're choking." and performs the Heimlich maneuver on him immediately. When someone is choking, the first thing a trained responder does is to ask the person if they can talk, and see if they get a response. If they do, that means air is able to move through the trachea to some degree, and it allows the responder to decide on an appropriate course of action (have the victim try to expel it by forceful coughing, providing back blows, or if the Heimlich Maneuver is appropriate). One would never just start with the Heimlich, especially if you could hear the person speaking, as CJ could when she ran up.

While it is true that Brody should have started by checking the patency of the victim's airways, then given two respirations (drowned patient) before starting the chest compressions, there is no reason why his partner would stop him from doing the chest compressions: she could just check the mouth and prepare for respirations.

Mitch would not (as a lifeguard) throw his opponent through a window to risk his death but rather incapacitate him.

Mitch would not (as a lifeguard) laugh at the thud he just threw in the pool but get to him quickly to make sure he will not drown.
