The Doctor From Gallifrey 

Matt Smith popped up on tonight's edition of CBBC show Blue Peter to launch this year's Script to Scene competition where primary school children have the chance to write a mini-episode of Doctor Who. Last year they created Death is the Only Answer which you can view on our Mini-episodes page.

Here's the Matt Smith clip which oddly enough is a sort of sequel to the Second Doctor story "The Mind Robber". It's set in the same place anyway!
