Written and directed by Indian filmmaker Dhruva Harsh, Do I Exist: A Riddle seeks to combine René Descartes’ philosophy “Cogito, ergo sum” (“I think, therefore I am”) with Buddhism to explore the possibilities of life after death. Equal parts Christopher Nolan and Terrence Malick, the film questions the notion of reality by filtering its narrative through these philosophies, culminating in a thought-provoking and dreamlike meditation.
