Kenny Baker was the actor inside R2-D2 in the six Star Wars films. Turns out he doesn’t have a ton of affection for his fellow droid.
On a number of occasions, Baker described his less than warm feelings for Anthony Daniels, the actor inside C-3PO. In a 2009 interview with Metro he offered the following:
"I thought it was just me he didn't get on with but recently I've found out he doesn't get on with anyone. He's been such an awkward person over the years. If he just calmed down and socialised with everyone, we could make a fortune touring around making personal appearances. I've asked him four times now but, the last time, he looked down his nose at me like I was a piece of s**t. He said: 'I don't do many of these conventions - go away little man.' He really degraded me and made me feel small - for want of a better expression. He's rude to everyone though, including the fans."
