I'm Not Very Glamorous.

I Used To Be Absolutely Addicted To The Gym And I Do Still Love It.

I Was Very Much Into Science When I Was Young - I Wanted To Be A Marine Biologist, Then I Wanted To Be A Doctor, And Then Something Else, I Was Always Changing. Acting Didn't Come Up Until Much Later, Probably About 16 Or 17. I Thought, "oh, I Quite Like This."

I Found A Lot Of Comfort In The Fact That 30-odd People Have Been Companions Before Me. I Think That When There Are So Many People Contributing So Many Things To The Show, All You Can Do Is Make It Your Own. You Can't Try To Emulate Anyone, Because Who Would You Pick? The Companions Are Very Much The Everyman, And The Audience Watches The Story Through Their Eyes, So They Could Be The Person Next Door. And Everybody's Different.

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.
