His second film, "Juno", generated great buzz after it premiered at the 2007 Toronto International Film Festival and was released in December 2007. It was Roger Ebert's favorite film of 2007 and received Oscar nominations for Best Picture, Elliot Page's performance as the title character, Diablo Cody's original screenplay, and Reitman himself for Best Director. Reitman did win other awards for his work on "Juno", including Best Director at the 2008 Canadian Comedy Awards. The film grossed over $140 million at the U.S. box office, making it the largest success of Reitman's career and more successful than any of his father's films since "Kindergarten Cop". Brad Silberling was originally attached to direct the film, but he dropped out over casting differences. Reitman was in the middle of writing a screenplay when he came on board to direct "Juno" and, at one point, he expressed intent to finish writing and to direct this screenplay.
