Carlos Fuentes had a rich life in politics – and was the Mexican ambassador to France at one point in the late 70s.  But his heart belonged to writing.  His novel, Gringo Viejo, or, The Old Gringo, was made into a movie in 1989, starring Gregory Peck.  A contemporary of Gabriel Garcia Marquez, he himself returned to magical realism in his last novel, Destiny and Desire, which was set in modern Mexico.  He just died at the age of 83.  And you can hear his interview with Leonard from January 2011, in which he discussed Destiny and Desire, and his life in, and out of literature.
