Other mistake: The rope is wound round Jack's body and the pole at his back numerous times. When Shishka-Jack falls, the pole gets jammed between the cliffs, but the pole does not break and the rope does not tear. The rope that goes round the pole numerous times simply disappears, leaving the rope intact around only Jack's body in order for Jack to twirl and unravel as he falls. This is impossible, and done for the humor.

Other mistake: The first time the Kraken attacks the ship, he breaks it clean in 2. One of the guys is right next to the tentacle when it breaks the ship, yet he is launched up into the air. If he was next to the break he would be pulled down into the water, the only way he'd be launched would be if he were at the opposite end of the boat.

Other mistake: Whilst the crew are escaping Pelegosto, Jack climbs onto the boat and he is hit by a wave and he gets soaking wet. But if you look before he gets hit by the wave, you can see his clothes are already soaking wet, and his chief make-up has washed off before the wave hits him.
