Continuity mistake: When Matt Brody goes on the "American Ninja" course to prove his ability as a lifeguard, and holds on to wooden sticks in holes, the sticks are on the 1st and 2nd holes. When camera angle changes, they are in the 2nd and 3rd holes. (00:25:35)
Continuity mistake: When Mitch and Matt are on the jetski headed out to the burning boat, Mitch tells Matt to take the throttle, and we see both of Mitch's hands remain on the steering, but in the next shot Mitch has the rescue can's shoulder strap hanging across his chest, which has suddenly appeared between shots. (00:38:05)
Continuity mistake: When Mitch, Matt and Summer go to the morgue to check the body of Councilman Rodriguez, Summer stands near the door while Matt and Mitch check the body. You can see a reflection of Summer on a window showing her facing the door, then as the camera cuts between Matt and Mitch she is looking away, then she is missing her white coat, then she is shown taking it off and instantly has a green top under her blue scrubs. (01:08:00 - 01:09:00)
Continuity mistake: When they enter the morgue Mitch doesn't have shoes on. When he runs out after the bad guys, he is wearing shoes. (01:11:11)

Continuity mistake: Zac Efron has no shirt on while lifting and competing against Dwayne Johnson, then the people fall and jump off the pier - he hops on the motorcycle which has a green shirt on the back, and in the next shot he's suddenly wearing that shirt.
Other mistake: During the yacht fire, only 3 people are saved, 2 dark hair girls and a guy (Councilman Rodriguez), but when on land, 3 girls are being questioned. Where did the blonde come from?
Suggested correction: The blonde was the one who Dwayne Johnson speaks too.
