Um, I fail to see the comparison between the ridiculousness of a 9 year old Anakin claiming he was going to marry Padme, and artistic liscense ADF used by not following the script 100% (even less connection with things like Jabba, which WAS 100% accurate at the time the novel was written).

Also, it isn't just 1 line from the novel, Terry Brooks didn't make it up or add it, it was in the script, written by the godlike hand of George. This line is also referenced in Weird Al's song The Saga Begins, with the line "he said is gonna marry her someday..." Al put the line in the song, because it was in the script that Lucas gave him to read shortly before the release of the film.

Concerning the ridiculousness of a nine year old boy stating that he wanted to marry an older girl, there is nothing ridiculous of this in of itself, the ridiculous part is the nine year old eventually actually marrying her. As rcb's point was, Lucas was trying to make it a Romeo and Julietish love story. Aww he has been in love with her since he was nine, how sweet! ...!
