have been wondering since day of the doctor why they could not have used the eccleston part of the footage from 9-10 regeneration ad reversed it, then stuck it on the the end of the war doctor regeneration e.g war doctor starts to regenerate, then use that old footage in reverse so instead of eccleston going into a regeneration it looks like him coming out of the regeneration. I know they would have had to alter the background but i'm sure they can do that these day's, and the best part is that it is footage the already own so presumably would have needed no consent from eccleston himself
