When Andrés (Fele Martínez) meets Alicia (Elena Anaya) inside a movie theater, one of the films announced is "Abre los ojos" (1997) by Alejandro Amenábar, in which, curiously, Fele Martínez plays the role of Pelayo.
Andrés has hung in his apartment, among others, the poster of "Después de tantos años", a documentary about the Panero family, directed by Ricardo Franco in 1994.
