Is it legal to make a film with lightsabers in it in a different universe than Star Wars? Is it legal to make a sci-fi films where there are no Jedi, but people wield lightsabers that are very similar to the ones in Star Wars? Assume for the sake of the question that every character in the film is blue-skinned and they wield orange-colored lightsabers and it's set in a sci-fi universe completely different from that of Star Wars. Is this considered a derivative work and thus infringes copyright, or can it be considered to be an original just because the setting is different?
