20He Originally Had Short Ears
Say what you will about Jar Jar Binks, but you’ve got to admit that the design team did a good job solidifying a highly recognizable and unique look for the Gungan. In addition to features that recall the amphibians in our own galaxy, he’s got lanky humanoid limbs that are
perfect for wacky slapstick comedy.
However, according to Doug Chiang, Jar Jar originally had short ears which were later elongated per George Lucas’ request. Lucas thought that having long flappy ears that would flop around whenever Jar Jar turned his head added to the character’s comedic elements. The decision led to other changes, like giving Jar Jar giant eyes on stalks that could pop out for comedic effect.
