No, they’re not a new kind of fruit snack. (To my knowledge, that is.) They’re the opening words that you see crawling or "rolling-up" the screen at the front of Star Wars movies.
As the date for the release of Episode III: Revenge of the Sith draws nigh (it’s just over a month away), Lucas has let slip (minor) spoilers for what is to come. (Major spoilers are also available all over the Internet for those who are inquisitive.)
One of the things he has let slip is the roll-up for Episode III, which is posted on the official site. It has minor spoilers (the crawls tend to set up the movie but don’t give away much of what happens in it), but for the spoiler-timid, I’ll post it here in white-on-white so you’ll need to Select All or swipe to see the text:
Episode III
REVENGE OF THE SITH
War! The Republic is crumbling under attacks by the ruthless Sith Lord, Count Dooku. There are heroes on both sides. Evil is everywhere.
In a stunning move, the fiendish droid leader, General Grievous, has swept into the Republic capital and kidnapped Chancellor Palpatine, leader of the Galactic Senate.
As the Separatist Droid Army attempts to flee the beseiged capital with their valuable hostage, two Jedi Knights lead a desperate mission to rescue the captive Chancellor. . . .
