Jorge Rodríguez Paz is a real life actor in Peru and has appeared in all the titles he describes in the film as well as in other famous films ( 'What the Eye Doesn't See' from 2003 and 'The Motorcycle Diaries' from 2004 among others) later on.
The soccer match playing in the radio at the beginning of the film is the one disputed by the countries of Peru and Uruguay on July 13th 1993. The exact date of the match can be determined because of the players selected to play in the Peruvian team on that occasion versus Uruguay.
Most likely, it was a match to determine what countries would be classified to the 1994 FIFA Soccer World Cup in the USA.
