My father was a coal hewer from Goldthorpe, a coal-mining village in South Yorkshire. He played for the Yorkshire second team as an opening fast bowler - to me he was a gorgeously heroic man. He helped form a union and closed down the Barnsley seam because it was seeping gas, and saved many, many lives.

I've completed half of my space training at Space City in Moscow. I love adventure, and I've been training in a centrifuge and MiG Fighter with a view to going into space and being a spokesman for space exploration!

The misapprehension about me is that I am some loud, rampant maniac. I am actually very pensive and quiet.

People talk about the difference between radio acting, TV acting and stage acting, but I think it's all the same. For instance, when I played Vultan in 'Flash Gordon,' I put as much energy into it as I would with 'King Lear' - it's all part of the same thing.

I've become quite a serious explorer: I've been to Everest three times; I'm the oldest man to reach the North Pole; and I've just been to the lost world of Venezuela.

The household I grew up in... was rather like an Ovaltine advert. There was a huge fire, a kettle on the fire, the oven with the bread being baked every day, and there was the radio; it was very magical to hear all these wonderful programmes.

I can't retire from life. I love life too much and I cannot wait to start the day.
