It depends on the area that you live in. In some areas they may have sword fighting clubs usually HEMA or SCA. In some parts of the US, and parts of the world, even African Martial Arts, C.B.T., Kendo, FMA and a few others. Yet these are COMBAT arts that teach you how to repeatedly stab, slash and kill people. If you want to learn that then yes go to a local combat sword fighting school.
Yet NOT for 'MOVIE Sword Fighting Training'. Understand this...Movie Sword Fighting for Film & TV is to movies…What Stunt Fighting is to movies…PERFORMANCE ART. It is learning how to deliver SAFE, believable, realistic, compelling sword fighting performances on camera with movie prop swords (i.e. the Star Wars Franchise, The Witcher, Game Of Thrones, Spartacus, The Villainess, Crouching Tiger Hidden Dragon, etc.) not actually stabbing and hurting people with real swords like in combat sword training (which is fun by the way. We also teach this as well).
Combat sword training does NOT translate well to film & TV performances. Many of the techniques are too dangerous and would actually hurt or kill the other performers in the project. It’s designed for combat after all. Plus many of the techniques are not very cinematic and thus don’t look good on camera. And it can take months or years of practicing several times EVERY week to become proficient with it.
Movie sword fighting, on the other hand, is DESIGNED to look good on camera and to be able to be learned and used in a short period of time (this is how it works in film & TV). There are rules for SAFETY on set, guidelines & drills for practicing with your scene partners, rules for delivering sword strikes, performing for camera and more. While combat sword fighting is about killing or maiming your opponent as quickly as possible (within 1 - 3 moves), Movie Sword Fighting is about NOT stabbing or hitting your opponent yet SAFELY generating the ILLUSION that you are stabbing or killing them. It’s performance art that has it’s own rules, techniques and must be studied like any other artform.
