Stick-Dat-Twist

The scene went something like this… Discovered alone in the homestead garage by an insomniac Padmé-concerned by the sudden departure of her fledgling murderous boyfriend- she asked if Threepio was happy. He soulfully confirmed that he was not unhappy, and that indeed everyone there was very kind and considerate. He only regretted that Master Ani had been made to leave so quickly-a midichlorian problem as far as I remember-and had no time to finish his handiwork as maker and add the requisite coverings to his creation. It was very difficult to be like this. “This?” enquired the feeling Padmé. “Naked!” replied the ashamed and sensitive droid. “Naked! It simply wasn’t protocol!” […] Moved by this confession, Padmé’s eyes dropped to the empty floor where she found at her feet a box of coverings. “I never noticed,” said the astounded droid, while admitting that he was not very mechanically minded, in a manner of speaking-possibly an admission of total blindness would have been more accurate. Gracefully bending to rummage in this newly noticed treasure chest, the sharp-eyed ex-queen found another chest and a face and more besides.- Anthony Daniels

The scene ends with Padmé putting the chest piece on C-3PO. They wrapped at 7PM. On July 10, shooting resumed with scene 116: early the following morning C-3PO is almost fully covered and Padmé has only the face mask to put on.

For the scene, Tony wore the whole costume except the front of the head, and C-3PO’s eyes were over Tony’s eyes. We put magnets inside the headpiece, so that when Natalie set the mask onto the eyes it locked into place. - Don Bies (Droid Unit Supervisor)
