Visible crew/equipment: When the Black Knight falls off his horse (the same scene where you can see a truck in the background), to the right of the screen you can see a man who is wearing a modern day brown suit and a cap, standing with his hands in his pockets and watching the action. (01:29:25)

Factual error: In his fight against Dennis and the Jabberwocky, the Black Knight uses a flamberge, a very distinct two-handed sword (note the little "crescent" hooks on the blade). The only problem is that these swords are a German design from the 15th century, more than 200 years after the movie is said to take place.
