In the opening teaser footage, there is a scene in which Starbuck, while training the female cadets, says "Remember, you're flying a Viper. Thinking what you want it to do is enough to make it happen." This doesn't appear in the actual episode.
Jonathan Harris plays the (uncredited) voice of the Cylon Lucifer. Earlier, he played the evil Dr. Zachary Smith in another space television series called Lost in Space (1965)
