Filmmaker Jason Reitman is all set to start another. It is said that his new film will be an adaptation of the book Up In The Air written by novelist Walter Kirn.
Jason's father Ivan Reitman owns the rights to the novel. This film with budget between $12 to $15 million is expected to start shooting by the end of this year. Walter Kirn's novel Thumbsucker was also adapted as a feature film in 2005.
