The Witches actress moved to New York from California to star in new TV sensation Smash, but before Huston left the West Coast she decided to set herself a personal challenge - which ended badly.
She tells Britain's Radio Times, ""Before I left California I was determined to ride all of my horses in order of difficulty. Start with the easiest and go to the hardest. When I got to the sixth and hardest horse I had a big fall.
""Somehow I knew it was coming and I was lying on my back staring up. It was humiliating. It's nothing to do with how good a rider you are, but it's almost as if you have to learn how to become good at taking a fall. You have knowledge of it before it happens. It's a peculiar thing, but it's about risk-taking. You are probably going to have a fall but you do it anyway.""
