Two Undercover Angels was part of a three-picture deal director
Jesús Franco had with the production company Aquila, run by
Adrian Hoven,
Michel Lemoine and
Pier Caminneci.
Two Undercover Angels was the second of these productions. It was a West German and Spanish co-production, developed by the Munich-based Aquila, and Films Monta S.A. based in Madrid. The film was shot between September and October 1967, just weeks after the Berlin premiere of Franco's first Aquila-funded film,
Succubus (1968). Among the cast was
Janine Reynaud. She was the wife of Lemoine, and had previously worked with Franco in
Succubus. The film was shot between September and October 1967. Location shooting included several locations in Spain, including
Alicante,
La Manga del Mar Menor,
Archena,
Portmán,
Madrid and
Marbella as well as some in
Munich in West Germany. Interiors were shot at Estudios Roma, S.A. in Madrid. The American theatrical cut originally released as
Sadisterotica is different from the original Spanish theatrical release. This includes changes in when the credits appear, some editing, and cuts the cage dancing in the night club sequence while the American version removes the North African establishing shots. The Spanish version of the film was scored by Fernando Garcia Morcillo. The film score of the American version of the film by
Jerry van Rooyen was played during the montage when Franco accepted won his honorary
Goya Award in 2010. ==Release==
