Hamill shares 1st pic of Luke

Mark Hamill is here to rescue your weekend with some good old-fashioned nostalgia. The "Star Wars" actor shared a photo Saturday morning of himself as a young Luke Skywalker posing in the Tatooine desert on the first day of filming "Star Wars: Episode IV -- A New Hope." He stands with his hands folded across his heart. "Taken in Tunisia early morning day [number one] waiting for my [first] shot (emerging from home for robot auction)," he wrote. Hamill has played Skywalker since 1977's "A New Hope," the first installation in the Star Wars movie franchise.
