I think both videos may or may not be legal in terms of Fair Use and U.S. copyright laws. Both videos give credit to the original name “star wars” on their video titles. The presentations and message are different from each other. The star wars saga is just scenes from the original movie but with different background music than the real star wars theme song. Even though they use some scenes from the original movie it may not be legal because the U.S. copyright office states “copyrightable works include the following categories: motion pictures and other audiovisual works”. The other video is just trying to advertise Mt.Dew. Although the same characters are in both videos they have different physical appearance. These videos may not be legal because the U.S. copyright office states “Only the owner of copyright in a work has the right to prepare, or to authorize someone else to create, a new version of that work.” This is basically saying that no matter how much you change you need to ask for the owner’s permission in order to make those changes. These videos are tricky to explain if they are legal or not.
