I Was Very Much Into Science When

I Constantly Make Lists And Itineraries And Then Can't Stick To Any Of Them.

I Always Have To Have Breakfast Before I Leave The House, Even If It's 4 A.m. And I'm Not Hungry.

David Tennant Is A Massive Fan, And Grew Up Dreaming He Would Be The Doctor Who One Day. So I Did Feel, When I First Got The Job, "right, Now I've Got To Do Loads Of Research Into Absolutely Everything Doctor Who." But That's Not Possible To Do In A Short Space Of Time. So My Knowledge Has Been Growing And Developing As I've Been Doing It, And That's Been Fine. That's Been Appreciated By The Fans, And The Executives Never Expect Me To Be Brushed Up On Absolutely Everything.

Being Short Works For Me.

I Couldn't Sustain Myself If I Skimped On Food - I Work 16-hour Days, I Need The Energy, I Can't Afford To Be Stingy On What I Eat.
