The Illiterate One (Spanish: El analfabeto) is a 1961 Mexican comedy film, directed by Miguel M. Delgado, starring Cantinflas, Lilia Prado, and Sara García.
An inheritance attorney sends a letter to Inocencio Prieto y Calvo telling him that he is the heir to his uncle's fortune of two million pesos, which he has only to claim by producing his baptismal certificate as proof of identity.
He leaves without telling the druggist his problem, resolved to go to school and to wait to learn the letter's contents until he can read them for himself, so that never again will he have to share private matters with others because of his own ignorance.
Leaving the bank, he meets Blanca, an attractive young woman newly arrived in town, and shows her the way to her new place of employment, partly to avoid admitting he cannot read the written address.
On the day of the contest, Aníbal and Fermín, who are revealed to be cousins, conspire to make it appear that Blanca has stolen her employer's jewels and passed them to Inocencio.
However, Pilcher also stated that "the movie featured Moreno's strongest supporting cast in decades", singling out Ángel Garasa, Carlos Martínez Baena and Sara García.
