Plot hole: When the group first finds the plane, they are all able to hold their breath long enough to descend, search the plane and resurface. Yet later in the movie, even though Amanda can get a full breath of air from the air pocket in the plane, she can't hold her breath long enough to swim to the surface and has to be rescued by Jared.

Visible crew/equipment: In the scene where Scott Caan's arm is caught under the cannon and Paul Walker lifts it to get him out. When the cannon is dropped back to the ocean bottom an air bubble floats to the surface. As the camera follows the air bubble a camera man in the water is visible on the right side of the screen next to the boat.

Continuity: In the airport scene Scott Caan introduces his new "girl" to Paul Walker and Jessica Alba. In the background behind Paul you see a long-haired brunette wearing a strapless shirt walk out of the terminal and continue past the camera. The shot changes to a wide angle of the four main characters, and a second or so after the change you see the same brunette come out of the terminal again.

Continuity: When they are pulling the cannon onto the boat, about ten minutes prior to the end, there is no water on the cannon, it is completely dry though it just came out of the water.

Revealing: During the scene where Paul is mad at Scott for not telling him he had no money to buy a boat, the mic wire is visible outside Paul's collar.
