Woody Allen + Larry David + the process for making a feature-length film - all but about 2 minutes of the footage = the trailer for Whatever Works.
An eccentric New Yorker played by Larry David abandons his upper class life to lead a more bohemian existence. He meets a young girl from the south and her family and no two people seem to get along in the entanglements that follow. This is a comedy also starring Ed Begley Jr., Patricia Clarkson, Conleth Hill, Michael McKean, Evan Rachel Wood, and a number of other amusing types.
