The film is inspired by the true-to-life story of the discovery of the long-lost “Opus 28” manuscript from Norwegian composer Johan Halvorsen, originally performed in 1909 by Canadian violinist Kathleen Parlow, to whom the piece was dedicated.
Campbell portrays a student who seeks to complete her thesis on Parlow by organizing a public performance of “Opus 28” from Toronto to Oslo. The cast includes Dueñas, Melanie Scheiner, Eve Duranceau, Maxim Gaudette, Rosa-Johan Uddoh, and Eileen Davies.
My Dearest Señorita, produced by Javier Calvo and Javier Ambrossi, is an adaptation of the 1972 Oscar-nominated film of the same name directed by Jaime de Arimañán, who co-wrote the script with José Luis Borau starring José Luis López Vázquez.
