Leonard Kastle
Leonard Gregory Kastle (b. 11 February 1929) is an opera composer, librettist, and director, though he is best known as the writer/director of The Honeymoon Killers, his only venture into the cinema, for which he did all his own research. He was educated at the Curtis Institute of Music and the Juilliard School. He is a member of the SUNY Albany faculty.
His operas include Deseret (1961), on a libretto by Anne Howard Bailey about Brigham Young, which he directed for NBC Opera Theater. He writes in a Romantic style that the music academy does not hold in high regard as something for contemporary composers to do. His favorite composer is Gustav Mahler, who was not at all respected when he was in music school.
Kastle has also written The Pariahs, about the sinking of the whaling ship Essex, a trilogy of operas about the Shakers known under the collective title The Passion of Mother Ann: A Sacred Festival Play, a children's opera called Professor Lookalike and the Children, a piano concerto, sonatas for piano and violin, and three unproduced screenplays, Wedding at Cana, Change of Heart, and Shakespeare's Dog.
In a 2003 interview for the Criterion Collection, he said that no producer wanted Wedding at Cana, just another Honeymoon Killers, which he did not want to do.
