The Real Thing at Last (1916)
The Real Thing at Last is a satirical silent movie based on the play Macbeth. It was written in 1916 by Peter Pan creator and playwright J. M. Barrie as a parody of the American film industry. The film was made in response to news that American filmmakers intended to honor the 300th anniversary of William Shakespeare's death, and presents itself as a crass example of how they would adapt the classic play.
