It's the 50th year of Doctor Who and look what's going on! We're up in the sky and under the sea! We're running round the rings of an alien world and then a haunted house.

If this wasn't already our most exciting year it would be anyway!

I like that Helen Mirren has been saying the next doctor should be a woman. I would like to go on record and say that the Queen should be played by a man!
