I remember being told very early on, 'Just say what they want to hear in the audition, and we'll figure it out later on.' So there have been a few tricky moments. I once said I could ride, when the truth is I'm terrified of horses, but I got the job!

I had this maroon 'Lion King' tracksuit that my mum couldn't take off me. I wore it until the sleeves ended at my elbows and the trousers ended at my knees.

There's so much fakeness in the fashion world, but Mum and Dad have always given us a good work ethic and were quite worried at first about whether I could make a living from acting. They've been together for 29 years and share the same values. I really do want to have that kind of marriage myself.

It's never fun having to bulk up for a job on an action film, then lose weight for another role. I don't actually mind working out, but it's the diet: I'm half-French, so I love my food, and boiled chicken breast for breakfast is not my idea of a good meal.
