Visible crew/equipment: The scene where Spencer throws the boomerang for the first time and misses the bikers they take off running. While they are running from the bikers, there is a shot right before the boomerang hits the bikers where you can see a camera man sitting in the bushes on the left side. You don't have to pause it, but can to see it better. (00:36:30)
Continuity mistake: When the sharks attack Jack and Henry's rowboat, one bites a chunk of the stern and the hammerhead bites a chunk of the bow. In following shots the bow bite vanishes as the shark leaps over Jack and Henry when it lands in the water, and the damage at the stern not only changes, but it also vanishes when the shark imitates Bruce from Jaws and lands on the boat.
Continuity mistake: Gargamel finds out of the smurf he captured is Smurfette. She grabs the bars of the cage, but the position of the door hinges changes, switching from her right to her left, back and forth. (00:13:35)
Continuity mistake: When Shawn first holds up the jerky to distract the guard dog, he's holding the torch in his right hand and the bag of jerky in his left. We cut to a wider shot and the items have instantly switched hands. (00:26:50)
Continuity mistake: When Castillo shoots through his own partner, he falls down with his butt roughly where the yellow line on the asphalt is. When he is shown again, he's lying down some meters away. (00:06:40)
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: The third time after Rob reawakens in the elevator, when he bumps into the man with the micro-brew, the amount of beer spilt over the man's shirt increases between shots. (00:29:15)
Continuity mistake: When Tommy comes to pick up Greg on the street where Greg was playing with some kids, Greg goes to get in Tommy's car. As he walks around it, a kid with a burgundy striped shirt is standing by the car with the football, but as he's getting in in the next shot the kid changes to the green shirt kid holding the football. During this part of the scene, the kid by the car changes back and forth between the green shirt and the burgundy stripe shirt kid several times. (00:06:10)
Continuity mistake: As students are watching porn, Strickland struts his way down the school corridor through jumpcuts. Some extras in the background have poses radically different nobody could switch to without reason, like this blonde guy who is turned the other way and that suddenly is leaning against the wall with his arms crossed while Strickland has barely walked one step.
