This article reviews 77 bibliographical sources about Before Night Falls (1992) and its film and operatic rewritings. The aim of this study was to synthesize, analyze, and discuss the bibliography around these works. Based on theoretical-conceptual affinities, the sources were grouped into three categories: gender studies (29), self writings (29), and film rewriting (18). It is concluded that there are still research gaps that justify to delve critically into the work and its rewritings, by using theories such as queer, the role of the author, narration in the screenplay, among others.
