Factual error: The wrestler is killed by Snake stabbing the back of his head with a spiked bat, having rather long and thick spikes on it. As the Wrestler falls against the net, the back of his head is shown as he is slumped over the net. There is no wound on his head, nor any trace of blood, despite having one or more large spikes just jammed into it.
Factual error: When Air Force One crashes into the office building, the security force monitors show the escape pod falling to the ground - inside the building. Normal physics would dictate that the pod would 'slide' across the floor of the building it crashed into, not smash through 20 floors towards the ground. We can assume the buildings are in disrepair, but it has only been 11 years since the island was turned into a prison.
