Write & Wrong (2007)

Quickly approaching her fiftieth birthday, talented and once-famous screenwriter Byrdie has lately had a hard time finding work in the movie biz. As she's aged, the industry hasn't, and the new regime isn't interested in what a maturing wordsmith has to say. In desperation, Byrdie dreams up a script-selling scheme, enlisting her attractive nephew Jason, a car salesman, to pitch her work as his own. The ruse is a wild success: All the key players eat up his charm, and her scripts soon become the hottest thing in town!
