Re: Should Matt SMith's doctor age before regenerating
I did not know that about the End of Time. This is interesting -- do you know why they decided against it?
I would guess any number of reasons. They save time and money by not putting age make-up on Tennant, even if it is just something simple like making his hair gray. They risk it being too much of a distraction if they don't get it just right. The desire to see the Doctor in his traditional look the last time we see him, which I believe is the reason for why his cuts, bruises and scars instantly disappear after his radiation exposure begins the regeneration process.
