Carmen (1915 Cecil B. DeMille film) so DeMille instructed his screenwriter brother William to base his scenario on the public domain novella "Carmen" by Prosper Mérimée. The novella's Carmen was more wilful and manipulative than the opera version. For instance, William included a cigarette factory fight scene from the book which was not found in the opera. Composer Hugo Riesenfeld arranged the orchestral score, his first of many for film, which "was" based on that of Bizet's opera. It was performed at the premiere and other prestigious screenings. There have been two restorations of Riesenfeld's score: the first was by Gillian Anderson, recorded with the London
Opera in Canada motet style, tonal folk song and the twelve-tone technique. John Beckwith's "Night blooming Cereus" (1958) is another example of Canadian themes in opera and a “parable of the redemptive powers of love” in a small town in southern Ontario. It also features southern Ontario vernacular music and texts. During the 1960s the construction of many new theatres and the establishment of new opera companies resulted in the production of many new Canadian operas to be performed on stage. Healey Willan's "Deirdre", first composed in 1946 for a radio broadcast of the CBC, was revised and performed on stage in 1965.
