"Sei personaggi in cerca d'autore" by Luigi Pirandello is a play written and first performed in 1921. Six mysterious strangers interrupt a theatrical rehearsal, claiming to be unfinished characters abandoned by their author. They demand their dramatic story be staged—a scandalous tale involving forbidden desire, family secrets, and tragic consequences. As the bewildered director attempts to bring their narrative to life, the boundaries between reality and performance dissolve, leaving everyone questioning what is real and what is merely acted.
