The movie was adapted by Alan Bennett from his play, The Madness of George III.
An urban legend circulates to this day that the Roman numerals were removed from the title of the film because U.S test audiences misinterpreted them to mean it was a sequel. This, however, is untrue [1].
The film was directed by Nicholas Hytner.
It won the Academy Award for Best Art Direction, and was nominated for Best Actor in a Leading Role (Nigel Hawthorne), Best Actress in a Supporting Role (Helen Mirren) and Best Writing, Screenplay Based on Material from Another Medium.
