In both Die Gespenster von Flatterfels (1992) and Alle meine Töchter (1995), Fritzi Eichhorn and Floriane Eichhorn shared the same role. This is one of the few films in which the twins play a different role from one another.
Glenfinnan Viaduct, featured in a shot early in the film during the train ride, can be seen in many other films and television series, including Charlotte Gray (2001), Monarch of the Glen (2000), four of the Harry Potter film adaptations, Ring of Bright Water (1969), Stone of Destiny (2008) and Cri de Coeur (2019).
