I had to look tan and fit to play the ex-leper in Life of Brian, so I ran up and down the beaches in Tunisia where we were shooting. I got back to London and I thought, I must try and make running a regular thing, and I have ever since.
I’ve been running for 32 years. The idea of stopping at any point is just inconceivable.
The idea for my movie “The Missionary”  came to me while running, and it was completely different from what I’d set out with. I finished and let the concept unscramble from my mind.
There was a time when I used to run wherever I was in the world, but I’ve gotten a little bit lazier now, and I tend to go for the hotel treadmill.
That said, I once ran around an entire island [Bird Island in the Seychelles Archipelago] before breakfast, though it was just a few kilometres.
I only do two runs a week – around eight to 10 kilometres. I go after a morning’s writing work and before I eat anything.
I come back from my runs with more energy. I’ve gone out with hangovers and when I’ve had a cold coming on. Always, I finish feeling better.
I don’t know if being a runner makes you funnier. My wife certainly laughs when she sees me running!
I don’t track my runs at all. I know if I’ve had a good one or not. If it’s a beautiful sunny day, I run a little bit longer.
My most important piece of running gear? Probably my front-door keys.
The last five minutes of my usual run, I go up Parliament Hill and get a great view across London. That’s always a great bit, just to see the city spread out before me.
I wouldn’t mind dying while I was running. I think it would be quite a good way to go – if it was sudden.
