I didn't want to break with my family. I wasn't about to make waves. But I had this feeling I wanted to do something that I liked to do. Acting's what I liked to do most. There must have been a moment when I felt, 'Oh, my God, I like this and what am I going to do about it?'
I think the crux of the matter was that if we were going to become partners in, for example, the International Space Station, we had to gain the respect of a country like the United States and particularly its space organization, NASA.
