I love characters who are clever and smart, and you have to run to catch up with. I think there's something very appealing and rather heroic in that.
David TennantHow galling to watch someone who looks like you, who basically is you, do all the shagging you didn't get to do.
David TennantAnd the very fact of how you speak somehow influences who you are. The way you move, the way you think, it seeps into your being, and it's quite hard to really break that down entirely.
David TennantI'm quite happy to leave it still feeling that way, leave it before it starts feeling like a job. ... I have such fond memories of watching 'Doctor Who' when I was a kid and growing up, that if I've left anybody anywhere with memories as fond, then I feel like I've done my job.
David TennantI think it would be self-indulgent to go, "Oh, I'm going to make this character different by giving him a quirk of some kind." I don't think that serves the story, particularly. But even very similar scenes with a different set of actors, a different set of circumstances, it starts to evolve as a different character.
