I've Basically Grown Up With Harry Potter,

I Think When You Get On With The Actors That You're Working With, Even If You Do Have Really Intimate Scenes, As Long As You Get On Well, And Have A Bit Of A Laugh While Doing It, Then It's Fine.

It's Not Work, It Is More Of A Passion. It Is So Much Fun And It Is Really Makes You Feel Great At The End Of The Day. You Feel Like You Are Really After Doing Something Good And You Are After Accomplishing Something. Acting Is One Of These Things That I Can't Really Describe - It's Just Like, Why Do You Love Your Mum And Dad? You Know, You Just Do.

When I Was Younger, I Would Mess About And Have A Laugh With Everyone. I Was Doing Atonement When I Was About 12, And As We Went To Do This Very Serious Scene, The Director Joe [wright] Came Up To Me ... I'd Been Giggling Right Up To The Beginning Of The Take. And He Came Up To Me And Said, "okay, You Need To Be Serious Now." I Completely Idolized Him.

I Certainly Don't Feel Like I Am Desperate To Run Away From A Film Set. I Love The Hustle And Bustle. Everything Is Sort Of Mad Right Before A Take, And Then It Just Settles, And You've Got These Two Minutes Of A Bit Of Magic. I Just Love That In Film.

I Remember Being On Atonement And It Felt Very Right To Be There. There Was So Much Excitement Every Day. I Remember Very Vividly How It Felt To Be A Child On A Film Set, And That Is Actually Really Important To Hold On To For As Long As You Continue To Make Films.
