They are desperate to see the trailer, called Breathing, to Star Wars Episode II: Attack of the Clones, which is being shown before Monsters Inc.

The trailer was shown first in Britain on Newsround on CBBC One on Monday - and you can also get it by following our website link on the right.

So what's it like?!

Light sabres

The first thing you notice is the familiar sound of Darth Vader's breathing.

This continues throughout the entire trailer, only broken near the end by a loud crash when two light sabres smash into each other.

Clone troopers

Among the images are shots of Anakin and Amidala kissing, bounty hunter Jango Fett flying with his jetpack, and Yoda and Mace Windu looking annoyed.

There are also a number of different spaceships flying at great speed, a light sabre battle lit only by the sabres themselves, and a final shot of thousands of clone troopers preparing for war.
