This book explores how classical and Shakespearean tragedy has shaped the temporality of crisis on the stage and in time-travel films and videogames. In turn, it uncovers how performance and new media can challenge common assumptions about tragic causality and fate. Traditional tragedies may present us with a present when a calamity is staged, a decisive moment in which everything changes. However, modern performance, adaptation and new media can question the premises of that kind of present crisis and its fatality. By offering replays or alternative endings, experimental theatre, adaptation, time travel films and videogames reinvent the tragic experience of irreversible present time. This book offers the reader a fresh understanding of tragic character and agency through these new media's exposure of the genre's deep structure.
