"But, apart from that, there was very little on underneath the suit"

This quote by Peter Mayhew is describing his experience playing the iconic character of Chewbacca in the Star Wars films. He is referring to the fact that he was wearing a complete body suit while playing the character, which there was very little beneath the fit. This quote is likely describing the reality that he was using the fit for extended periods of time which it was rather uneasy. It might likewise be interpreted as a metaphor for the character of Chewbacca, as he was frequently portrayed as a strong and powerful character, but underneath the exterior, he was still a gentle and kind-hearted animal. This quote is a pointer that despite the fact that we may appear to be one way on the outside, there is typically a lot more to us than satisfies the eye.
