I added the hyphen to the film's title, to make it consistent with the other films in the "trilogy" (so that they all get picked up by a search for "one-armed swordsman"). Also because it's better English

I put the hyphen-less version as an alias, to make sure it would be caught by whatever people searched for...

Oh no, the dreaded h-word...

Different kettle of fish this time!

He is "The swordman who is one-armed", not "The one swordsman who is armed"... that would be a whole different film (but probably about the same body count :p)
