Yes, I thought of that and forgot to ask Prime -- when exactly did Lucas make the aforementioned statement? Was it when Anakin was appealing to Palpatine for the power to save the life of Padme? I assumed it was, and that's what threw me. I could more likely imagine him saying "the Dark Side is more powerful" during a battle or something. (Even so, isn't it strange how Yoda doesn't get beaten by the baddies?)
