The inventory process and stepping back in your life can sometimes be a very dark process. But it also can be extremely funny and surprising.

I'm busy and that's the way I like it - when I have too much downtime I get into trouble.

There was never any career plan. When 'Red Dwarf' started I thought we were doing a curious little sitcom on BBC2, I didn't think I was becoming an actor. I didn't see that 21 years later I'd still be talking about it, let alone filming a new one. For me everything's always been an accident.

Prison widens your circle of friends. In my stand-up, I can now talk about things that no one else has the right to touch.

British fans are exceptional, but the American fans are something else. Some of them fly 500 miles to stand in line for three hours, just to meet me, then when they do they collapse.

I've got wealth and fame but I haven't changed my roots.

It's not supposed to be easy, if it's easy, it's no good, that's the way I look at it.
