I know 2, the 2 that are in the movies:
1. In ep. 2 where Obi and Aniken fight Dooku.
2. ep. 6 the fight between Vader and Skywalker.
That's all I have.
"They'll hunt me; They'll condemn me; Set the dogs on me; Because that's what needs to happen. Because sometimes, the truth isn't good enough. Sometimes, people deserve more. Sometimes, people deserve to have their faith rewarded. Not because they want to, not because of chance, but because they deserve to."
-Batman (From TDK)
