10 Star Wars Moments Actors Didn't Know Were Coming
2. Hayden Christensen Yelled Boo - Revenge Of The Sith
Order 66 is one of the biggest events in the Star Wars universe to date. Emperor Palpatine finally said those magic words that triggered the clone army to turn on the Jedi and hunt them down, to near extinction.
There have been several different scenes depicting what happened in the immediate aftermath, from The Clone Wars, to The Bad Batch, to The Mandalorian. But of course, the most famous depiction is seeing Anakin Skywalker face down the Jedi younglings on Coruscant.
The iconic scene shows Hayden Christensen walking up to the Jedi children, igniting his lightsaber, and then cutting away before he slaughters them. In order to make this scene as authentic as possible, at the time of the lightsaber kicking into gear, Hayden Christensen actually yelled "Boo!" in order to surprise and scare the young actor opposite him.
Ross Beadman, said young actor, told a Reddit Q&A that Christensen did this to add fear into his reaction, and it worked perfectly. Christensen was widely criticised for his work in the Star Wars prequels, but as moments like this demonstrate, he brought much more to the table than he gets credit for.
