@Dantha Fodder: The clips with Titanic music are just for playing around. They would never get into a serious edit of ROTS. But there are some people who like those scenes with Titanic music and they told me it makes them wanna cry and I like them too. So, playing around with music from other movies can make it feel different, but not necessarily bad.
I did something with the end of Episode I with music from a very popular movie and the result is astonishing and makes me wonder whether I should try a new edit of Episode I or not. It would have a length of 90 minutes, but I don't know if I will find the time and mood to do it. Editing the music is nearly the most difficult thing in editing a movie. You have to rebuild the sound effects because they can't be seperated from the original music, and sometimes it's even the same with the dialogue. If I decide not to do it, I will post this clip here, in hope that there's an editor somewhere outside there who want's do this one.
