One of the strangest experiences one can have is to sleep on stage, as I once did in Sydney when I'd lost the key to my flat. I had to stay at night in a bed, which conveniently was on stage because my character Sandy Stone did his monologue from a bed. To wake up looking at a shadowy auditorium is a very peculiar feeling.

A lot of people give actors credit when they gain weight for a role in a drama when they win an Oscar, but when you're doing a sitcom, people don't give you a lot of credit, because you've got to keep your weight on for five or six years if it's successful.
