During the filming of Filha da Mãe, several compelling stories and dynamics emerged among the cast, especially due to Canijo's intense and intimate directing style. Known for his raw and realistic approach, Canijo heavily emphasized extended rehearsals and genuine bonds between the actors to fully capture the emotional depth required for their roles. Rita Blanco, a frequent collaborator of Canijo, brought an authentic portrayal to her character, Maria Ribeiro, largely influenced by the trust and creative freedom Canijo fosters on his sets. This environment allowed actors to improvise and build complex, multi-layered performances, enhancing the realism that defines Canijo's work. The cast, including Lídia Franco and José Wilker, was selected to explore the delicate nuances of strained parental relationships and the emotional conflicts demanded by the storyline. Rehearsals were often long and intense, reflecting Canijo's technique of immersing actors in the emotional landscapes of their characters.
