If "Star Wars" is excellent at nothing else, it excels at bringing mechanical entities to life in an incredibly cute way. Chopper — also known as C1-10P — assists the "Rebels" crew with keeping the Ghost running. While the focus for much of the show's finale spotlights the rest of the team, the closing credits finally reveal whose voice was behind the loveable astromech. Though it was a mystery that might not have intended to make itself one, Chopper's vocal chops belong to none other than series supervising director Dave Filoni.

Though it makes sense to keep the expanding "Star Wars" family close to home, Filoni made sure that his involvement was a well-kept secret. As he explained at a fan event (via Comic Book) that was held after the series ended, Filoni explained that it wasn't his original intention to voice the droid. "I wound up playing Chopper ... we had to deliver the first short to Disney to watch and we didn't have a final Chopper voice. And I said, 'Alright, I'm going to just do this.' We did it right in the editorial in Lucasfilm," Filoni recalled. "I knew what a likable jerk is like and what I wanted him to be like. Then when we screened it, [Disney CEO] Bob Iger said, 'I really like that little droid.' And I was like, 'Well, now I'm stuck.'"
