More than one hundred blind or severely visually impaired actors, members of ONCE theater companies, perform eleven stories based on theatrical texts by a wide variety of authors, guided by Lucius, a blind Roman who wants to become an actor, and Thalia, the Greek muse of comedy.
Unfortunately the movie If Thalia Were Blind is not yet available on HBO Max.
