The studio logos, opening credits and a brief portion of this films opening scene is an Easter egg in the special edition DVD of Monty Python and the Holy Grail. The scene plays automatically if Play Movie is selected from the main menu unless the movie is already in progress. As the screen goes dark, a sputtering, unseen projectionist is heard fumbling for the correct reel of film a slide then appears urging the audience to wait while the projectionist changes reels. The correct Monty Python movies opening credits play properly from then onwards.
