Oe of the most difficult costumes for Deborah L. Scott was that of Sky Captain Peylak. She says: "I had done an initial version of a cloak, so I knew it was going to be suede leather, and I knew the basic shape of it; I had worked that out." However, after watching footage of actor David Thewlis's performance, she changed tack. "Watching him perform the character, he's so regal. He has this incredible posture and sort of strides through the environment, so Jim and I were both looking at it and saying, 'He needs to really look like the head of the clan.' So I went back in and redid all the designs.”
