Where could I start but just saying that this is the most intelligent movie ever written. Seriously, wait, nothing in this movie is serious. First off it contains the king of all comedy sequences, the almighty "Black Knight" sequence. We also get to learn about King Arthur's crusade, how to tell if someone is a witch, to beware of "killer rabbit's", how to deal with knights who say Nee, how to correctly answer questions to get across the bridge of peril, and how to get arrested while storming a castle. Not only funny, but essential for human survival. The extra stuff is most excellent. Michael Palin and Terry Jones go to the film sites and buy their own script at one castle and revisit the bridge of peril. We even get Lego Knights, and its a funny as it sounds. Extra stuff is just gravy. Really, if you don't have this one, you really deserve to have no movies at all.
