Sarduy's short documentary Guillermina (2019) had its world premiere at the New Orleans Film Festival. In March 2020 the Guatemalan Women's Association invited Sarduy to Madrid to talk about Guillermina.[3]
In October 2020 Sarduy spoke on race at NYU's Madrid campus. Arguing that race had been weaponised ever since it was socially constructed, she contrasted two options to deal with that history: negotiating a racial identity, accepting the existence and significance of race, or refusing entirely to accept race-based standards. Distinguishing different forms of racism (racism by conviction, programmatic racism, emotional racism and customary racism), she called for widespread re-education in Spain.[4]
