The last episode of Dr Who was pretty charged I usre enjoyed it. Although I heard rumours David Tennant was doing stage acting now, and so there will be a redcution in episodes next year.
Yep, he's one of the great mimics from Dead Ringers there's even a soundclip out there where he rings Tom Baker as Dr Who, and Tom Baker play along with him, turns out he rather fancied Davros.(I'd recommend this actor, he's very convincing!).
Another multiple Doctor ep would be cool, maybe something a little like this http://au.youtube.com/watch?v=VQEmGC6VK8k
