"I really don't think that you should get a statement tattoo that you can't hide — like neck, knuckles, hands — until you're over 25. Your choices change. I thought that I was going to be a rock star, so I went all out. Then I decided to be an actor.
It's a lot harder to walk into a room and be like, 'I'd like to do a period piece with Keira Knightley' when you look like you're from Trainspotting. I've been so lucky that makeup can cover it. You might think that you want to be in one industry, and then you might end up in more of an office situation — different places have different rules. I sound like a mum!
I love all of mine and they’ve told my entire life story. I love when I meet someone and I can see their stories through their ink. I think it's something that a lot of people use to express themselves. I obviously have. I have no regrets. I do think that if my mum had known that by getting rid of my tongue ring when I was 16, we're here 70 tattoos later, she might've been like, 'keep the tongue ring.' Make sure they have meaning and never get a partner's name; that’s the kiss of death."
