Good documentary, when will we get the other 3 parts ? :-)
A few points
1) why do you use only Williams' Oscar? I think a better way would be to start with a montage of all Star Wars oscars - I checked and all of them (or most) appear to be on youtube in pretty good quality
2) Obi-wan's scream - please use all versions, not just the first and the last
3) just a tip/question - do you plan to do a more detailed comparison of all (or the most obvious) changes done to Star Wars over the years?
