Jason Reitman is a Canadian-American film director, screenwriter, and producer, best known for directing the films Thank You for Smoking (2005), Juno (2007), Up in the Air (2009), and Young Adult (2011). As of February 2, 2010, he has received one Grammy Award and four Academy Award nominations, two of which are for Best Director. Reitman is a dual citizen of Canada and the United States. He is the son of director Ivan Reitman. Canadian-American filmmaker Jason Reitman later came upon the novel (initially attracted by the Christopher Buckley blurb on the cover) while browsing in the Los Angeles bookstore Book Soup. Reitman persuaded his father, Canadian-American filmmaker Ivan Reitman, to purchase the book's film rights, and the elder Reitman commissioned a screenplay from Ted Griffin and Nicholas Griffin, who used some elements from Turner's script in their work. Jason Reitman then developed his own screenplay, incorporating some of the original script that was (unbeknownst to Reitman) written by Turner.
