Apparently there's more to wielding a lightsaber than just slashing a broom through the air and yelling "whoosh!", and it's gotten a US man into legal trouble with Hollywood behemoth, Disney.

Disney – who owns Lucasfilm, the home to all Star Wars related property – is using its Force to sue Michael Brown, the owner of a handful of schools, including Lightsaber Academy and New York Jedi, that teach Star Wars fans how to use lightsabers for "illuminated stage combat" (aka, enthusiastic dork fights).

The lawsuit, filed by Disney on Friday, cites "cybersquatting, trademark infringement and unfair competition" amongst its complaints, a legal document acquired by The Hollywood Reporter shows.

Among those infringements are the academy's use of the Jedi Order logo on their website, "round in shape, with six wing-like shapes curving upward (three per side), and an eight-pointed star featuring elongated top and bottom points stretched into a vertical line," the legal complaint specifies.
