Paul Casey In Final Episodes

Paul Casey will be returning to Doctor Who to play the role of Ood Sigma once again. He has not said anything about the plot or the episodes he is appearing in but he did say "These final 4 episodes are incrediable and are amazing. Callum is lining up a very big cast with an unbievable story and he really has left the best for last. The Final Battle was a fitting send off for David Tennant and World's End is set to be a brilliant send off for Callum"

David Tennant has also spoke about the size of the story and has said "From what i've heard so far, the story sounds incrediable with an amazing cast and with fablous story. I would have liked to be apart of this story but i think Matt Smith is going to be very good in this story."

Callum has also revealed that he has now got the full cast for the final episodes and they will all be annouced over the coming months. Callum has also revealed that the oldest cast member is 55 and the youngest is 22. Karen Gillian is 22 so she is expected to be the youngest member of cast. This in some sense means Elisabeth Sladen won't be returning to Doctor Who because the prospect of her returning would also mean the appearnce of Thomas Knight who is only 17. This also means that Louisa Lytton will not be returning as she's only just turned 21 last month.

Callum has annouced the next cast news will be realsed sometime on Sunday and is going to reveal a big cast member for the final episodes.
