Chewbacca — Peter Mayhew
We daresay that no one else could have played Peter Mayhew. After all, it must be hard to find an actor who stands at 7’3.” It was not only the costume that made the character either. Mayhew perfected the body language of Chewy that when he fell ill during a shoot, the stand-in actor simply failed to get it right. Lucas did not use the footage they filmed with the stand-in. They simply waited until Mayhew felt better enough to return to the set.
