Xavier Lopez Rodriguez, comedian famous for portraying a huge boy named Chabelo, is credited as Jose Lopez Rodriguez "Chabelo".
The protagonists drive their taxis around Mexico City showing what was then still attractive: Tlatelolco building complex, Periferico freeway, streets of Lomas de Chapultepec. The movie shows the taxi cars of the 60s in Mexico City known as "cocodrilos" (crocodiles) because of their paint design: green/black decorated with jagged stripes (green reminiscent of crocodiles' bumps in their backs and white of their teeth.)
