Part of the problem is that Hollywood never wants to be negative. And face it … slavery isn't an upbeat topic.

The best way to control slaves is to convince them they are free.

Welcome to America, the Land of the Fee and the Home of the Slave.

When I first walked in to London, I was so overwhelmed by the village, the sheer volume of people. I was just so excited. You don't know what to expect. So the level of excitement was almost draining, just taking everything in. I was so exhausted after I swam because of all the excitement in the build-up.

I just always really wanted to swim. It was always a family thing: dad obviously swam, and my sister did, too. And mum used to come along to meets. They had to drag me out of the pool - so there was never any pressure on me to swim. It was just something I loved doing.

I wasn't even born when dad swam in the Olympics. I've seen videos of some of his swims, although I don't think I've ever seen him in the Olympics. He's been a massive support right through my career, and it's good to have someone so close to talk to who knows all about what it's like to compete in an Olympic Games.
