Regina enjoys the collaboration with dramaturges and theater directors, many times directing and/or choreographing for theater. She has a long time partnership with the dramaturg/psychoanalyst Antonio Quinet, with whom she directed Hilda & Freud, premiered in 2013 at the Freud Museum, in London, and then performed with variations in Buenos Aires and Rio de Janeiro. With the author, she also directed "Freudian Variations" (2011), and "-Open the Hysterics!" (2013). She is also proud of the play "Disfigured" (2006), that she directed and adapted with the actor Edilson Botelho. The play focused on the live and work of the famous visual artist Francis Bacon, and with the collaboration of set designer Niura Bellavinha, the light of Luis Paulo Nenen, and the great acting of Edilson Botelho and Paulo Marques, all reviews pointed to the 3D embodiment of Bacon's pictures and life.
