Don't ask me who my favourite monster was because I'm sick of saying Tom Baker.

I mean, I was first offered Princess Astra.

I was quite happy with the way I went, I think.

I think Douglas [Douglas Adams] was a real one-off. He was so clever and so intelligent and so well read in real science that he could make science fiction work as well as it did. And just such fun to have around, he was just such a lovely man.

We were only there for five days and during that time Tom was a bit annoyed that the French were more interested in me and my schoolgirl outfit than him and his long scarf.

Although the French were very friendly and helpful. On one location we were to film at the top of the Eiffel Tower but we couldn't, as it was so misty with four inches of snow on the ground. We couldn't see a thing but we finally got it done.
