Next to the studio where my daughter took ballet lessons (around 2011–2015), there was a shop where a guy sold second-hand clothing, bootleg DVDs, and other sundry goods. I sometimes went in to browse while my daughter was dancing, and he usually had one of his DVDs playing. There was one, in particular, that I remember making quite an impression on me—based purely on its visuals—that I might like to see again some time. It was probably less than a decade old when I saw it, so from some time in this century.
The film was Korean (I think; it is conceivable that it might have been Japanese), with a standard eastern sword-and-sorcery setting. I only saw about five minutes of the movie, but I asked the store owner what it was about, and this was what he told me: The protagonist was a powerful fighter, but due to some kind of curse (or perhaps a deal he had once made with a demonic entity), most of his extremities had been replaced by artificial limbs. (I think they were made of wood.) He was now on quest to win the rest of his body back, by fighting a series of monsters.*
The one monster that I saw him fight was a sort of giant crab or insect, larger than a human. The battle took place indoors, in a chamber surrounded by drab wood paneling.
*The description definitely sounds like the live-action version of Dororo, but I checked, and that was not the film I am looking for. It is conceivable that the store owner, who was not watching the movie very closely and had evidently seen it before, had actually confused the film he had on with Dororo and gave me a description of Dororo instead of the actual film that was playing. In that case though, there is probably little hope of me finding this actual film. (And I have learned about Dororo, which is cool on its own.)
