Emily Mortimer: voicing an animated car is the most "glamorous" role

The British actress voices sexy sports car Holley Shiftwell in forthcoming sequel `Cars 2` and was relieved she didn`t have to appear on screen because of her "bad" hair.

She said: "I`m convinced this is the most glamorous I`ll ever be in celluloid on this film.

"And luckily I don`t have any hair because my hair has always been my downfall. My hair looks really bad in all my movies so I was delighted to be a car that doesn`t have hair. I look better in this movie than I ever have or ever will look in any other movie.

"Even my agent complains about my hair."

Emily`s character is also an undercover spy but she insists she could never have based her portrayal on one of the glamorous women who feature in `James Bond` movies.

She explained: "I couldn`t do that because I knew if I tried to emulate a `Bond` heroine I would just fall flat on my face.

"I just had to be me in that world. My natural instinct was to just do what I would feel, which is just completely dippy and pathetic in that situation and that`s what I was doing.

"Then we realised that if she was out in the field, in this high-powered spy mission, she wouldn`t be quite so c**p as that so we developed it together over time."
