A Doctor Who Series 4 episode is to be called "Planet Of The Ood". This will obviously focus around The Ood who appeared in Doctor Who Series 2 in "The Impossible Planet" and "Satan Pit" where they were possessed by the devil like Beast. This news comes from the latest Doctor Who Magazine, out this Thursday. Personally I think the Ood are great and can't wait to see their return. The end of "Satan Pit" made me feel quite sorry for them.
