It was sad to hear of the death of Kenny Baker, actor for R2-D2. As others have pointed out, 2016 is proving to be a bad year for celebrity deaths.
Many years ago, I was in a conversation with a few mates at university talking about R2D2. One of them said that R2D2 was operated by an actor. I said that I read somewhere that it also had a remote control. To which my mate Dave responded with words to the effect: “maybe he’s inside the robot with the remote control. That way, if they have an remote control failure, they can switch to manual”.
Hope that isn’t considered insensitive. At the time, it made me laugh, anyway.
