Star Wars (1977) introduced us to many interesting characters, among them a perhaps under-appreciated C-3P0. In the original trilogy, Threepio had agency. He had purpose, and he played a key role in bringing down the empire. Threepio doesn’t always make wise decisions, but he does keep the action moving forward (or at least keep up with it). He’s intelligent, articulate, the intellectual partner of R2-D2. He tells R2 what to do, gives directions (“Come on, R2, we’re going”) and takes initiative - talking his way past the guards in the security room of the Death Star.
So what went wrong?
