Mortimer had to 'use wits' in unrehearsed Cars 2

Emily Mortimer says working on 'Cars 2' was similar to working with Woody Allen.

The actress – who voices sexy sports car Holley Shiftwell in the forthcoming animated sequel – says the lack of preparation and quick working speed on the Pixar movie was similar to that as when she worked with the famed director on 'Match Point'.
