Matt Smith comments: “It’s a huge privilege to be part of Red Nose Day, which is such a brilliant cause with so many brilliant people involved. It’s something that myself, Karen and Arthur have been very excited about and we hope that, as well as helping to raise lots of money, we can make you laugh along the way.”

News Of The World reported on Sunday that BBC One will air a 6-minute sketch for the charity event, featuring “two Amy Ponds”.

Red Nose Day 2011 takes place on Friday 18th March. Other highlights of the night will include sketches from James Corden, the cast of Outnumbered, Miranda Hart, Harry Hill, Steve Coogan and Armstrong & Miller. The charity helps to transform the lives of poor, vulnerable and disadvantaged people across the UK and Africa.
