Well with the ewoks problem I'm going to start by cutting the ewoks out as much as possible. Then I'm going to work in as many additional troops clips as I can. Then I'm going to try to incorporate as many of the wookiee shots as I can, but the problem here is that there aren't really any to work with. In RotS there are really only a few seconds worth of usable shots, and even these will require a fair bit of work. There is at least one clip from the Force Unleashed game where the wookiees are celebrating so I'm going to try to use that after the rebel victory. Other than that I don't know of any other sources of clips with wookiees so I will see what I can do with regards to recolouring and reusing the clips to try to expand it a little, however even then it isn't going to look great without expanding the original material. I also havent found any clips from other non star wars films that would be suitable, but if anyone has any suggestions I'm happy to hear them.
So to get round this I was thinking there are many shots where we see stormtroopers or rebel troops firing, and then it cuts away, and really there is very little movement, so I'm hoping to replicate this style of shot for the wookiees. Also when Han and co first enter the bunker, we see the forest behind them, here I will also add in some wookiees and other troops, again to create the illussion (because that is all any of this really is) of a large strike team.
As for Coruscant, there is a shot of some tie fighters approaching the surface of the death star which I noted as a possible change to have them approach Coruscant, and I'm hoping to create a new shot showing the Emporer's palace as being quite high, so that the majority of the views from the windows behind the Emporer will just be sky, though this could change. I hadn't really considered trying to make it mesh perfectly with the Coruscant from the Prequels because I don't think bringing RotJ in line with the PT would help to improve it. To be honest the name was the only thing I had really decided to keep, and even that is open to change.
The first motion clips I'm working on will be mostly rough cuts to see how well playing around with the storyline can work so I'm not sure if I'll upload those, however, the images I've been working on are more to give a feel of the changes to how things will look, so they have a bit more to show I think. Either way I will keep you all updated with the successes and the problems as they happen.
Thanks again everyone.
