Being offered the part of Nelson was kind of wacky, because I thought, 'Well, he had one eye and one arm,' and I thought 'Umm, I've been through this losing an arm before' (in Star Wars) and that wasn't too comfortable, but I reckoned if he could do it then I could do it.

So I looked him up on the web and I saw I wasn't too far from his age, or he wasn't too far from mine, and I thought it was pretty neat and a bit of a laugh really.

Would you have preferred to tackle the role of Byron?

I think possibly, until we started, I thought I was more of a Byron - more soulful and poetic. But frankly, because it's audio only, there is nothing to stop me being swashbuckling. He'd only got one arm, but you can't see it's only me on radio, so hopefully I sound a bit convincing. Time will tell.
