10 Scariest Star Wars Moments

10. Order 66 - Revenge Of The Sith

Revenge of the Sith did an admirable job of bringing the prequel trilogy to a close, and did so with more than its fair share of emotion and battle horror.

After the death of General Grievous and the birth of Darth Vader, Palpatine gives the fateful Order 66 to the clone commanders around the galaxy, who commence to gun down their Jedi leaders in cold blood.

Watching the Jedi fall, with the haunting music and Yoda's distressed realisation of what's happening acting as a background, is grade-A terror, where the film once more reminds fans that for all its fun characters and exciting adventures, Star Wars is actually a very dark franchise, willing to hurt its characters without pause.

So well done is the scene, in fact, that when Obi-Wan is shot down by his troopers, you can't help but hold your breath in fear - despite knowing he's going to be okay.
