Blindness

'A city is ravaged by an epidemic of instant \"white blindness\". Those first afflicted are quarantined'

Blindness is a 2008 dramatic thriller film that is an adaptation of the 1995 novel of the same name by José Saramago about a society suffering an epidemic of blindness. The film is written by Don McKellar and directed by Fernando Meirelles with Julianne Moore and Mark Ruffalo as the main characters. The novel's author originally refused to sell the rights for a film adaptation. The producers were able to acquire it with the condition that the film would be set in an unrecognizable city. Blindness premiered as the opening film at the Cannes Film Festival on May 14, 2008, and the film was released in the United States on October 3, 2008.
