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)
Visible crew/equipment: When the police woman falls off the boat when the shark hits it, on the right side of the screen, you can see a hand outstretched, as if reaching out to grab her. It doesn't belong to the only other person on the boat, since he's behind the wheel and completely out of reach. So, it belonged to a person who wasn't supposed to be there.
Visible crew/equipment: During Gibbons' funeral, when the camera pans up to eventually catch Vin Diesel sitting in the gallery, a few extras (such as the woman two rows behind the one with the flaming red hair) look up following the movement of the crane. (01:36:10)
Visible crew/equipment: When Peter approaches Happy in the beginning, you can see the camera reflected in his glasses. (00:06:26)
