Noelle 'almost' didn't get the part. There were two other big contenders. One was a very good actress whom I'd seen in a very experimental short film (she went on to teach acting), and the other was a very...well, a very busty actress, who was really quite talented.
So why Noelle? I felt she represented more accurately the image of the techy.
I never got to work with either of the other two women. I think both were a little offended that I didn't use them. Shame. They would have been great.
