Reclaiming the Blade is a documentary on a history of swordfighting throughout the years in real life and in the movies. Totally cool!
Yeah, I know it's not science fiction, but sword fighting/fencing has long been one of my interests (I'm probably the only one who ever watched Basil Rathbone fencing with Errol Flynn in various classic movies, wishing Rathbone would just skewer Flynn!).
So if you've ever watched the Star Wars light sabre duels with interest, check out the "real thing" via this documentary.
