With guest stars and musical promotion, the March 10 episode of FOX\'s "The O.C." has already been eventized -- to use the industry jargon -- to the hilt. Add another reason to visit with your favorite Newport Beach teens (and their randy parents) that Thursday night. As a special gift from 20th Century Fox, the new trailer for "Star Wars: Episode III - Revenge of the Sith" will premiere at some point during "The O.C."

The full-length "Revenge of the Sith" trailer will get its theatrical premiere the next day, attached to prints of the 20th Century Fox animated film "Robots." The completed George Lucas epic, the final part in a trilogy of prequels leading up to the trilogy that shaped a generation in the late \'70s and \'80s, will spread around the world on Thursday, May 19.

Naturally, FOX is offering no hints as to when the trailer -- featuring the film\'s stars Hayden Christensen, Natalie Portman and Ewan McGregor -- will actually air.

The March 10 episode, titled "The Mallpisode" also boasts guest stars Billy Campbell ("Once and Again") and Johnny Messner ("Anacondas") and a soundtrack highlighting five songs -- four world premieres -- from Beck\'s new album "Guero," in stores on Tuesday, March 29.
