A portrait of Sven Nykvist directed by his filmmaker son Carl-Gustaf, Light Keeps Me Company combines extracts from the remarkable oeuvre of the legendary Swedish cinematographer and interviews with an extraordinary array of film-world notables whose work has been touched by his brilliant visual style. Ingmar Bergman, Woody Allen, and Roman Polanski put in rare screen appearances along with directors Jan Troell and Sir Richard Attenborough; actors Liv Ullmann, Erland Josephson, Susan Sarandon, and Gena Rowlands; and fellow cinematographers Vilmos Zsigmond and Lazlo Kovacs (who also contributed to the shooting of the film).
