Fair use and copyright laws have become a big deal since the rise of websites such as youtube and the creativity that modern day computers bring us. Videos such as “Star Wars Saga” allow us the take small pieces or “clips” of video and piece them together in any way we want while adding our own sound effects over it including music as we see in this video. The video is considered a “parody” of the original Star Wars movie and while parodies are often seen as having their own original ideas and not blatantly stealing from the original, people have been sued before for creating parodies so it’s ultimately up to the Federal Court to decide.
The other video, “Star Wars fan film: The Essence of the Force”, is a parody in the form of a mountain dew commercial that uses ideas from the Star Wars films, but doesn’t use any video or audio clips from the original movies. It instead uses ideas created by the Star Wars films such as The Force, the Jedi Order, and lightsabers. While it doesn’t directly take anything from the original films, the ideas and objects that the fan film takes from the original are very famous ones that are often seen in the media. If they used ideas or objects trademarked by George Lucas or the company associated with the original films without permission, then they are indeed violating copyright laws. I believe LucasFilms may have a trademark over some of these so the people who made the fan film could very well be violating some laws and pay for it if it attracted attention from LucasFilms.
