I always wear the shoes of the character a week before going on set; the idea of just putting on a new pair of shoes on the first day of filming is just horrific.
That's one of my jobs, just trying to do what I can to help this team out as much as possible.
Well, I had a lot of help from my father with the soldering and so on, and he was very good at math and was fascinated with computers, and so I was fortunate enough to have a bunch of exposure going all the way back to high school - this was in the 1960s.
