Richard Dean Anderson: (about the scar over his left eye) It's part of what we established in the character. We have to maintain it because it will grow over, and believe me, it's a pain in the butt to be walking around with this bareness there. It was one of those elements of movies and television that has always driven me crazy. So, I can't remember the episode, but I got hit in the eye or slugged or something, and we established a big bandage and the whole thing, and I told Jan [Newman, make-up artist], you know, this would leave a mark. Let's run with this. Let's keep it in there as part of what defines O'Neill. And so that's all it is. It's just a character thing.
