The Solitude of Prime Numbers

Director Saverio Costanzo

Production year 2010

Length 118min.

Country Italy/Germany/France


A prime number is inherently a solitary thing: it can only be divided by itself, or by one; it never truly fits with another. Alice and Mattia also move on their own axes, alone with their personal tragedies. As a child Alice’s overbearing father drove her to a terrible skiing accident, and then to anorexia. When she meets Mattia she recognizes a kindred spirit, and Mattia reveals to Alice his terrible secret: that as a boy he abandoned his mentally-disabled twin sister in a park to go to a party, and when he returned, she was nowhere to be found. These two irreversible episodes mark Alice and Mattia’s lives forever, and their destinies seem irrevocably intertwined.
