R2-D2 sounds
R2-D2 is probably one of the only film robots that we actually have a real emotional connection with. The android has been there with our heroes through thick and thin and has always pulled through in the end for them during tough times. But did you know where the beep sounds it makes originally come from?
Well, the sounds that are made by R2-D2 are actually human baby noises that are heavily altered in a studio. Apparently, this is a common practice to achieve multiple sound effects in movies. Sound people really have to get creative to capture certain noises that most of us have never heard before in our lives.
