Keira: I did a film called The Hole when I was 16 and, when it came out, a couple of the popular girls at school said, quite loudly, 'She's in a crap movie, so it doesn't count.' It was rude and I was upset, but if you let that stuff bother you, you're going to be in for a tough time. I wasn't popular at school. I learned to let those comments wash over me. I toughened up quite quickly.
