Rare Star Wars Photo: Mark Hamill as Luke Skywalker

This photo shows a young Hamill on the Tatooine set in Tunisia. This photo belongs to Ann Skinner, who was the continuity supervisor on the original 'Star Wars' set and would be displayed through Jan. 4 in London in the Atrium at BFI Southbank as part of BFI's sci-fi festival 'Days of Fear and Wonder.'
