Star Wars director George Lucas will guest-star as himself on The O.C.'s May 12 episode, Fox confirms. In the episode, Lucas expresses interest in Seth's (Adam Brody) "graphic novel," which leads Ryan's better half to make a difficult decision regarding Summer. Things become even more complicated when Lucas invites Seth to dinner and gives him some worldly advice. I'm guessing it sounded something like this: "Seth, man, if you missed 24 last night, get a tape. Chloe was fierce!"
