Nos anos 70, eu me lembro de Lucas dizer que ele queria que o C3PO fosse um "slimey slick-o usado em um revendedor de carros", mas assim que Anthony Daniels começou a falar, ele transformou o personagem no que todos nós conhecemos.
Então, o personagem está lá principalmente para o alívio cômico, assim como o próprio Daniels. declarado :
What’s your favorite and least favorite line of C-3PO dialogue? My favorite line is — interesting you ask least favorite — my favorite line is, [in character as C-3PO] “We’re doomed.” It’s a phrase that encapsulates his whole philosophy. It’s his life. He always feels on the edge of disaster. That’s where the humor comes from because he is a humorous character, but mostly it comes by default. He doesn’t tell jokes. He’s just wrong about everything most of the time and lives on this precipice of fear, which gives a sort of tension. You and I hide that. You hid magnificently that you were terrified of talking to me. As humans, adults, we sort of do. He doesn’t have that guile. And in fact, now that I come to think of it, he is pretty much without guile. He says it as it is and that can occasionally be quite funny because he can be inappropriate without meaning to be. This is the thing that George and the writers originally created and we’ve taken it further and further. There’s no way I can think of the situations he’s put into, but they sometimes let me tweak [his lines]. In fact, they always let me tweak the script.
Além disso, ele também conhece mais de 6 bilhões de idiomas, então eu penso no C-3PO mais como um intérprete do que como um diplomata.
E para responder a sua outra pergunta, sim, houve outros droides rudes:
- o outro droid de protocolo no Cloud City foi rude com o C-3PO
- R2-D2 foi rude com os droides no Jawa Sand Crawler
- E havia outros droides no rastreador de areia torturando dróides e restringindo-os
