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.

For me, everything has always been an accident.

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

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

We were the only black family in an estate with 1,000 white families. Liverpool being quite racist in the Sixties, it was a bit grim growing up.

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

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.
