Factual error: At the end of the film when the news reporter says 'Isn't that the guy who had the skunk on the freeway?' then you hear a voice calling him back to look at the camera. This is wrong, as if they wanted his attention on the camera, then they would call him through his headset.
Continuity mistake: In the scene where Crocodile Dundee is hiding in the jungle after taking the painting; as he comes out from hiding with his arms up he is facing the other people, but in the next close up shot, his head is looking up his own arm. There isn't time for him to have moved it.
