It is based on the novel "Dejarse Llover" by Paula Farias.
When B (played by Tim Robbins) consults his book regarding getting around the cow in the road, there's a very noticeable coffee ring stain on one of the pages. The movie The Hudsucker Proxy is about Tim Robbins's character coming up with the idea of the hula hoop because of a coffee ring stain. Remarkably this stain had no bearing or relation to the Hudsucker Proxy. Its a coincidence.
