I do not believe that the Star Wars Saga violates copyright for a number of reasons, namely that it doesn’t affect the market share of Star Wars. Since it’s a video on youtube with a fairly small number of views and can in no way be considered a substitute for the original work. Another factor to consider is the nature of this work compared to the original. While this work emphasizes the musical score (not from Star Wars) and utilizes the video clips from Star Wars merely to provide emphasis. In addition to both of these it only uses a very small fraction of the original work. Given the fact that there is also a lack of the Star Wars movies sounds in the clip it conveighs a very different message than the one that the movies did.
The Star Wars fan video is not a copyright violation for a different reason entirely. A copyright only protects the actual thing, not the idea of the copyrighted work. Since the fan film didn’t use any of the actual footage or names, they should be free of any legal trouble. There is a slight question though about the fonts and logos that they used; specifically the ones for the production companies. Last I checked the criteria for copyrights on that was whether they could be confused for the company in question, and Fox and Lucas Films could easily make a case that this is the case.
