Damien Echols wants Paul Dano to play him in an upcoming movie version of his new book, “Life After Death.” Echols was released as a death row prisoner last year after 18 years as one of the so-called West Memphis Three, and he’s produced a new documentary on his case, titled “West of Memphis,” with “The Hobbit” director Peter Jackson. The doc, which opens Christmas Day, has gained fans including Johnny Depp. Dano was at a New York premiere of the film at Florence Gould Hall Friday with his actress girlfriend Zoe Kazan, “Hobbit” writer Fran Walsh, Sean Avery and Eve Hewson. “Damien and the producers really want Paul [Dano] to play Damien if the film based on his book moves forward,” said a spy at the event.
