tiptopper:
Even films about the future have swords as weapons, for example, the light sabers in Star Wars.
While the "Star Wars" motion pictures were 'futuristic' in some ways, technically they were set in the past.
However, I agree with you about the use of swords--there was even an original "Star Trek" episode, "Day of the Dove," in which the Federation forces and the Klingons were swordfighting, although it involved a rather contrived plotline...
