But it was in the script and it does describe Lucas tendency to over describe things and not use the less is more approach. He does not allow his audience to imagine things, see the new wampa for instance in 1997 empire.

But frink is right its not in the finished video, but it had been intended to be included in the dlp version but they did not put it into the movie.

After all Lucas had also intended earlier on to have Han Solo in Revenge of the sith as a 13 year old in believe and Chewie's adopted brother, so at least that was dropped as was making palpy, Anakin's father, who created him through manipulation of midichlorians taught to him by Darth Plagueis.
