Reitman's first film, Thank You for Smoking (2005), earned him buzz; his second, Juno (2007), was the darling of critics and audiences alike. His third, the zeitgeisty Up in the Air starring George Clooney in one of the best performances of his career, as a corporate downsizer with a fetish for flying snagged six Golden Globe nominations and four Oscar noms. With two career Academy Award nominations for Best Director, the Canadian-born Reitman is one of Hollywood's youngest success stories.
