This chapter examines the interactive complexities of book-to-film adaptation of Villaverde’s novel, as exemplified by the relatively faithful 1949 version and Humberto Solás’s knowingly unfaithful 1982 remake. The two film versions’ very different responses to Villaverde’s literary work are case studies in the application of fidelity issues as a frequent focus of adaptation theory. The chapter discusses the impact on film production of casting decisions, plot reconfiguration, political or ideological influences, etc. Other filmic adaptations discussed include María la O, La última rumba de Papá Montero, Un paraíso bajo las estrellas, and Tony Nodarse’s animated short film.
