Oxfam 'unwrapped' by Leo Burnett

Oxfam has shown that it can keep up with the Tescos and the Marks & Spencers of the world by enlisting a load of celebrities to launch its Campaign for Decent Christmas Presents.

Dame Helen Mirren, Helena Bonham-Carter, Will Young and funny-man Rob Brydon all line up for Leo Burnett's first campaign for Oxfam Unwrapped.

In the 40-second execution, filmed like a classic charity ad, the celebs make pleas to end rubbish present buying while holding, well, rubbish presents. Brydon has a moving stuffed pig.

The objective is to encourage people to buy gifts for others that can really make a difference to their lives.
