"At first, McCallum said, he thought that the thought of love turning Anakin to the Dark Side would be a difficult concept for the hard-core "Star Wars" fan base to accept. "I'm amazed nobody's had a problem with that whatsoever," McCallum observed. "They can all identify with that. It's like your mother having cancer or your sister being hit by a car -- there are so many things subliminally in people's lives that make them relate to him, but it was a very tough concept on paper to get through."
I have a problem with it

Another quote from the article:
"We thought about it," McCallum said. "One of our assistant editors did the dialogue that George wrote for him. It was one line. It was never during shooting, but in post-production. He did a little Liam sound-alike but it just didn't work, (the scene) was more powerful without it. There was so much buzz about it on the Internet that Liam actually called me to find out if there was any truth to it. I said, 'No, we're going to do it without you this time.' You could feel that there was a presence of him there."
Un-fucking-believable. If this is true, McCallum needs shooting.
