As little kids Litri and Pelopunta go to a theater where Copper Canyon (1950) is the movie playing. However, Litri, born in 1930, would have been 20 years old when that film was first released. Also, their reason to go to the theater is to see a documentary about Manolete's latest bullfight playing before the movie, and Manolete died in 1947, three years before Copper Canyon's release, and when Litri is already an adult according to the movie.
