Answer: R2-D2 and C-3PO
Known on the screen as the friendly and inseparable duo, the actors depicting R2-D2 and C-3PO shared none of the feelings of their personalities on the screen. During an interview from 2009 with Metro Magazine, Kenny Baker, the actor in the R2-D2 suit, said about Anthony Daniels, the actor in the C-3PO suit:
I thought it was just me he did not continue but recently has I discovered that he is not moving on with anyone. He has been such a troublesome person over the years. If he just calmed down and was socialized with everyone, we could make a fortune trip around making personal appearances. I have asked him four times now but then he looked down at me as if I were a bit of s ** t. He said, "I don't do many of these conventions ̵1; go away the little man." He really worsened me and made me feel small – to have a better expression. He is rude to everyone, including the fans.
Let yourself think that the feeling of mockery was one-sided and Mr. Baker simply misunderstood Daniel's feelings on the issue, we let Daniel's words clear things up. In a 2011 interview with The Mirror, he explained:
I never saw him. I mean, R2-D2 doesn't even speak. He might as well be a bucket.
What the story between the two may mean in addition to their public comments, we fully understand if you prefer Jedi to deceive yourself into forgetting this trivia tidbit and continue to love the adorable on-screen duo as they were presented in the movies.
