Oliver Jackson-Cohen

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.

The closer I get to retirement, the more I feel it will be a huge change, a shock, because athletics has been the core of my whole life. I know I'll miss the feeling of running fast, the adrenaline rush, and hearing the crowd cheering me on.
