Modernism has emerged as the preeminent iconic representation of Barcelona. However, the process through which this peculiar style has attained its iconic status is an arduous and multifaceted endeavor. This paper examines the challenges inherent in the categorization and periodization of Modernisme, followed by a succinct review of its initial filmic representations, culminating in a comprehensive analysis of two films in which Modernisme assumes a pivotal role: All About My Mother (Pedro Almodóvar 1999) and Vicky Cristina Barcelona (Woody Allen 2008). We conclude that Modernisme’s transformation into a cultural brand is largely attributable to the erosion of its ideological component in favor of a touristic and globalizing gaze.
