Yikes. Droid bitterness is a real thing. 

Anthony Daniels, who brought the Star Wars' franchise C-3PO to life, is not a fan of actors who play droids and don't do it the hard way. The hard way being what he had to go through almost 40 years ago when A New Hope was being filmed. 

Alan Tudyk, who plays K-2SO in Rogue One, told Conan O'Brien recently on Conan that he was cussed at by the British actor when he visited the Rogue One set. 

"Anthony Daniels went on about the suit that he had to wear and that 'originally they put screws in my head and they closed it' and he had to be on this thing," Tudyk, best known for his work on Firefly said. "He said, 'Wait a minute, are you wearing an actual robot costume, or are they doing it in motion capture?'"

Tudyk replied it would be motion capture, to which Daniels said, "You shit." 

But, that was not the end of it.

"And then I saw him at the premiere, I said hello again, and I said, 'I'm going to ask you for notes when this is over, if you can please tell me how I did.' And I saw him at the party afterwards and he came up and said, 'f— you.' And that's one of the best compliments I've got!"
