'Big-headed' comedian Jimmy Carr was in Kingston's Market Square this morning filming an advert for Comic Relief.

The giant sized replica of his cranium was built to promote a new flavour of crisps named after the TV star.

He is currently competing against Frank Skinner, Stephen Fry and Al Murray to sell the most packets of the snacks.

For each sale of Fry Up, Frank Roast Dinner, Jimmy con Carrne and Steak and Al Pie, Walkers will donate 5p to Comic Relief.

The winner will be announced on Red Nose Day on March 18.

The losing three will face the indignity of being waxed on national TV.

Kingston Council's filming unit brings in money to the council coffers by renting out public spaces for TV, adverts and films.
