Just noticed the other night that John Hurt does the voiceover for that Muller Corners advert with the cow running on the beach. Why? He doesn't need the cash. He doesn't need the exposure. I assume he doesn't just madly love thier product. So why do it? The the manufacturers have photos of him in a compromising situation or something?

See also: Stephen Fry (urgh) and Paul Merton doing Direct Line car insurance. Like Fry needs his mug around the place any more than it already is.

Which ones do you hate?
