O Último Trem de Madri

De Soto refers to "Damon and Pythias" in describing his relationship with the group of five soldiers. Damon and Pythias are figures from Greek legend that are used to demonstrate the meaning of true friendship. Damon trusted Pythias so much that he was willing to put his life on the line. This theme is echoed in the relationship between de Soto and Alvarez.

When Bill Dexter and Maria Ronda are going to see her father in prison, as they are handing their pass to a guard, a moving shadow of a crew member holding a boom microphone is visible on the wall behind them.
