I got into shape because I took kick-boxing lessons every day to prepare for a fight scene with Taylor Lautner. I really wanted to lie down and eat Chinese food but I kick-boxed every morning and ran. If someone was filming you with your kit off you'd do the same thing.
The strongest influences in my life and my work are always whomever I love. Whomever I love and am with most of the time or whomever I remember most vividly. I think that's true of everyone don't you?
