Some people live more in 20 years than others do in 80. It's not the time that matters, it's the person.

Back in 2005, when I was Christopher Eccleston, we saw one of the largest increases on record, of CO2 in the atmosphere. Unless we keep the rise in global temperature to under 2 degrees, by the time I'm Daniel Radcliffe or wee Jimmy Crankie, I won't be able to save the planet. I won't be here to help you -- well I might, but I'll be that bloke who won Any Dream Will Do.

I often stop when I'm doing something, in the middle of rehearsals or some other job, and I try to take a minute to think "Okay, this might be as good as it gets, so drink it in, appreciate it now". So far, I've been lucky because another job has always come along to equal the last.

Twitter! It's like being stalked by committee!

All roads seem to have come back to Doctor Who in our life. But, no, it was a huge part of my growing up. I was a massive fan and it certainly inspired me to get into acting and to be ... one of those people that tells stories on TV. That was a huge part of my childhood.

I remember a conversation with my parents about who the people on the TV were, and learning they were actors and they acted out this story and just thinking that was the most fantastic notion, and that's what I want to do.

How galling to watch someone who looks like you, who basically is you, do all the shagging you didn't get to do.
