What did you know about Star Trek when you auditioned for the part?

I knew almost nothing about Star Trek. I had flicked the switches from one channel to another and happened to pick it up. I saw what appeared to be very obviously styrofoam rocks and decided on a first impression basis that this was not going to be a terribly interesting show and never really watched it. I came on actually in the second season, so I was not there at the beginning. I was really very much surprised by everything that occurred. I had no understanding of the history of that first season.
