The movie Dolores watches while solving the picture puzzle is Rosemary's Baby (1968). The scenes playing on the screen mirror those in the film.
The English title of the film, "All of Them Witches", is the name of the book that Hutch (Maurice Evans) leaves Rosemary (Mia Farrow) when he dies in Rosemary's Baby (1968).
The film Andrés rents for Dolores is Benji (1974). Their dog is the same mixed breed as the "star" of that film.
