The nature of the link between a literary text and its film adaptation has been a point of contention within academic thought since the inception of cinema due to the fact that film adaptation forms part of film history since the early 20th century. For most of the past century, the main concern of critics has been the level of fidelity that adaptations exhibit in terms of their relationship with the text, which was viewed as "the original" that directors needed to use as a model. In the last 25 years, however, the discourse of fidelity has been challenged by a number of intellectuals as a result of poststructuralist thought, which rejects the notion of an "original" text and proclaims the existence of infinite meanings within each text that are constructed by the reader, not the writer. The present investigation will take into account this type of epistemology as its starting point in order to review and defy a number of theoretical approximations from the last several decades that deal with the relationship between literature and cinema towards its main goal of overcoming the limitations of fidelity discourse. This will be carried out through an in-depth analysis of Latin American texts that have been adapted to film. Thematically both the literary texts and the films contain elements that portray the reality of marginalized groups that build their existence in opposition to the model of patriarchal heteronormativity. In current epistemological thought such a modus vivendi falls within the realm of queer theory. Another common thread that unites all the cultural productions is the presence of violence that showcases the high level of intolerance towards any subject who somehow seems to be different, hence threatening the dominant configuration of patriarchy. Furthermore, the different texts and films expose a general fragmentation within Latin American society, a result of the constant struggles among its diverse social groups, between the ones who occupy the position of socioeconomic power and those who are left outside of it; such a fragmentation also stems from the multiple clashes that occur within the marginalized groups themselves.
