Mark Hamill, better known to many as young Jedi Luke Skywalker of Star Wars fame, signs yearbooks and other items for students and staff of Nile C. Kinnick High School. Hamill - in Japan on a publicity junket for the July 1st opening of "Star Wars" in Tokyo and Osaka - took a sentimental detour to his old alma mater which he attended as a military brat when his father - a Navy Exchange officer - was stationed at Yokosuka.
