First Mexican Film with Theremin
The Mexican film La Pantera Negra features the theremin prominently in the score and it is being distributed in theaters in Mexico this month.
The theremin part was recorded by Ernesto Mendoza. This is the first Mexican feature film to actually use a real theremin, and musically too! Although Mexican film companies released a lot of horror films in the 50s and 60s, they used a musical saw for the theremin-like tones.
