The Guinness Book of Records lists 410 feature-length film and TV versions of William Shakespeare's plays as having been produced, making Shakespeare the most filmed author ever in any language.
As of December 2017[update], the Internet Movie Database lists Shakespeare as having writing credit on 1,297 films, including those under production but not yet released. The earliest known production is King John from 1899.
In the British version, Lady Macbeth wiped a small amount of blood from her hands; in the American she had to wash away gallons of the stuff. In the British, the witches danced around a small cauldron; in the American the witches became dancing beauties cavorting around a huge cauldron. In the British, Macbeth and Macduff fought in a ditch; in the American Macbeth falls to his death from a skyscraper.
NOTE: "ShakespeaRe-Told", "The Animated Shakespeare" and "BBC Television Shakespeare" series have been covered above, under the respective play performed in each episode.
Three further episodes were filmed but never edited or screened. They were to be called "Using the Prose", "Using the Sonnets" and "Contemporary Shakespeare". Their text can be read in the book "Playing Shakespeare" by John Barton.
