I have a stepladder. It's a very nice stepladder but it's sad that I never knew my real ladder.

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

It's evolve or die, really, you have to evolve, you have to move on otherwise it just becomes stagnant.

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.

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.

Coming from having absolutely nothing to having a few grand in the bank, it was a big culture leap. I think that's why I went off the rails a bit really, 'cause there was no training for it. They didn't do fame in schools.

For me, everything has always been an accident.
