I can't dictate as fast as I can type; and I don't think in verbal terms,
I have to see it on the scren. I tried it once, but found I'm just not a very
good dictator (crew comments notwithstanding).

A guest actor really can't add much beyond the episode in which he or she
appears. But behind the scenes...some of our cast learned a lot while working
with Revell, and McCallum, and some of our other classically trained guest
actors. They were enjoyable experiences. As far as the experience they
had...all of our guests have to date expressed a hope to return in other roles
at some point. They've uniformly been treated well, and with respect,
particularly those who've made their careers in SF, and are viewed as "senior
officers" in a sense. Some have described it as the best working experience
they've had.
