Plot hole: The secret CIA base at Kamp Woody was underground. Kids searching for years have combed the camp, but never found it, but when Cody is going down the escalator, you can see bright skylights on the roof. If the sun is able to shine through, that means the skylights aren't hidden, and the kids would be able to find the camp.

Continuity: When Emily is spying on Cody on the sightseeing bus, she sits down and the camera goes to a close up of her face and we see small worm like camera device comes out of the right side of her sunglasses, but when it cuts to the next shot, further back from her face, we can see the device has disappeared even though no time has passed between shots.

Audio problem: When the trainer and Banks are fighting near the end where all the water jugs are, we here glass break when the trainer shoots that gun type weapon at the water jugs. But they are made out of plastic.
