Eroica - The day that changed music forever is a BBC television film that dramatises the first performance of Beethoven's third symphony, the Eroica.

The film was directed by Simon Cellan Jones, written by Nick Dear and starred Ian Hart, Tim Pigott-Smith, Anton Lesser and Frank Finlay. The music was played by Orchestre Revolutionnaire et Romantique and conducted by Sir John Eliot Gardiner. It won the Prix Italia for Performing Arts in 2004.

The film is set in Vienna on June 9, 1804, the date of the private, first performance of Beethoven’s third symphony, later to be known as the ‘Eroica’. The performance, and most of the action in the film, takes place at the palace of one of Beethoven’s patrons, Prince Franz Lobkowitz. Midway during the performance, Beethoven tries to get his lover, a widow named Josephine von Deym, to marry him, but she refuses because of the unfair laws regarding child custody - she is a member of the nobility, and cannot marry a commoner without losing custody of her children. Later, composer Josef Haydn, now old and feeble, arrives just in time to hear the last movement of the symphony.

A film, also called a movie or motion picture, is a series of still or moving images. It is produced by recording photographic images with cameras, or by creating images using animation techniques or visual effects. The process of filmmaking has developed into an art form and industry.

Films are cultural artifacts created by specific cultures, which reflect those cultures, and, in turn, affect them. Film is considered to be an important art form, a source of popular entertainment and a powerful method for educating – or indoctrinating – citizens. The visual elements of cinema give motion pictures a universal power of communication. Some films have become popular worldwide attractions by using dubbing or subtitles that translate the dialogue into the language of the viewer.

Films are made up of a series of individual images called frames. When these images are shown rapidly in succession, a viewer has the illusion that motion is occurring. The viewer cannot see the flickering between frames due to an effect known as persistence of vision, whereby the eye retains a visual image for a fraction of a second after the source has been removed. Viewers perceive motion due to a psychological effect called beta movement.
