'Sith' Darker Than Other 'Star Wars' Films

"It's just a much more emotional story, which is what happens because it is the climax of the first trilogy. And usually the first act is the introduction, the second act is introduction of the problem and the third act is the resolution. So this is where they get to resolve everything. Plus it gets to tie into the next film," Lucas told FOX News. "'I'm very happy — the film turned out very well. It's a bit of tearjerker ... it's very different from the other films. It's a bit darker," he added.
