Pessoa famously published under many heteronyms: around 75 different names, each with fully fleshed-out backgrounds, styles, appearances and philosophies. Taking this a step further, Não Sou Nada gives flesh to these characters, all working together under Pessoa, enacted by Miguel Borges, at the publishing house The Nothingness Club.
