The film was written by Don McKellar and directed by Fernando Meirelles with Julianne Moore and Mark Ruffalo as the main characters. Saramago originally refused to sell the rights for a film adaptation, but the producers were able to acquire it with the condition that the film would be set in an unnamed and unrecognizable city.
