Is it true that the Wampa ice creature attack was added to explain Mark Hamills injuries?
Mark Hamill was involved in a car accident shortly before filming on this episode began, which resulted in a broken nose, requiring surgery that resulted in some scarring on Hamill’s face. It has since become a popular legend that this attack was written into the story to explain the scars. However, this attack dates from the earliest draft of the script, predating Hamill’s accident. Lucas explains in the DVD commentary that this attack was merely to keep the audience interested while the Empire searched for the rebels, and to introduce the Obi-Wan Kenobi force ghost and, by extension, Yoda.
