Trivia, insights & behind the scenes
Ewa Aulin was fresh off 'Candy' (1968) and clearly paying rent between art films. This was her 'I'll do Euro-thrillers now' era.
Guerrieri was a genre journeyman who directed seven films in 1971 alone. This was Tuesday for him, but the paranoid structure anticipates later puzzle-box thrillers.
