It was one thing to include [Eccleston] among all the other archive Doctors, as they flew in to save the day – in fact, it would have been disgraceful to have left anyone out – but placing him in that scene might have given the impression he’d actually turned up for filming, which would have been crossing the line.Not taking part in the 50th was a difficult decision for Chris, taken after a lot of thought and with great courtesy, and not respecting his wishes would have been grossly unprofessional and disrespectful to a good man and a great Doctor. Number 9 may not have turned up for the celebrations, but there would have been no party without him.
