Mark Hamill briefly returns as Luke Skywalker in the newest installment of the Star Wars franchise. Now, he's teaming up with a California lawmaker on trying to end fake autographs. At the London premiere of the film, Hamill only signed a handful of posters. But when fans started seeing more and more autographs on the market, they asked Hamill personally, via Twitter, to verify. That action caught the attention of California Assemblywoman Ling Ling Chang. She was already hard at work on a bill that would make it harder for counterfeit memorabilia to hit tourist shops. The bill would require certificates of authenticity for signed memorabilia sold by dealers in California, as well as entitle consumers who were ripped off to as much as ten times the cost of the forged item in civil court.
