8. Kenny Baker vs Anthony Daniels
Although R2-D2 and C-3PO were inseparable on screen and admittedly bickered a fair bit, actors Kenny Baker and Anthony Daniels allegedly hated each other in real life. Artoo performer Baker referred to his co-star as "the rudest man I've ever met," and claimed that he was boring, annoying and never socialized with the rest of the cast â€” which makes him the perfect person to play his onscreen counterpart if you think about it... When Baker asked Daniels to do a tour with him, the diminutive actor says Daniels told him: "I don't do many of these conventions â€” go away little man." Wow, apparently one of Threepio's six million forms of communication is "being a massive d***."
