Boom mic visible: When what's left of Captain Thorpe and his men are coming back to their ship after being ambushed by the Spanish, you can see the shadow of a boom mic on the upper right portion of the ship on the screen.
Revealing mistakes: Captain Ortiz opens a door towards the end of the movie when he is running away from Thorpe and a string is visible, attached to the door. A sword slides down the string to give the impression that it is thrown at Ortiz and barely misses him.
Continuity: When the crew intercept a shipment of gold in the Panama forest, they fire multiple shots from muzzle loading flintlocks without reloading.
Anachronisms: The story takes place in 1588. The flint-lock muskets and pistols used in the film were not in use until two-hundred years later.
