The large majority of the film's scenes were shot in the Dolomites in Cortina d'Ampezzo, Italy. For example, the bridge scene was shot on Monte Cristallo in the via ferrata VF Ivano Dibona, which was reconstructed immediately after the movie. The climbing was mostly on the Tofane cliffs, and in some scenes toward the end of the movie the audience clearly sees the three Tofane, the Croda da Lago, and the town of Cortina; the location of this is on top of Mount Faloria, at the arrival of the funivia Faloria. In other scenes viewers may recognize the sentiero ferrato Astaldi, over the Rifugio Dibona. The small house has been constructed on the sand of the river Boite, in Fiames, close to the heliport. Some filming took place in Durango, Colorado. The credits of the film also thank the Ute Tribe for filming in the Ute Mountain reservation.
