There have been a few remakes of Sergio Leone’s first SW over the years, which of course was a remake of Kurosawa’s Yojimbo in the first place.
Anyway if you’re not already familiar with it, the Icelandic film Hrafninn Flygur from 1984 is at times almost scene for scene a remake of Fistful!
It’s about vikings in Iceland but the style and story is pure Leone Spaghetti-Western
It was a co-production between Iceland and Sweden, the Swedish title is Korpen Flyger, it also had an English title When the Raven Flies.
I’m not sure exactly in which countries it was shown though.
If you can find it it’s an interesting film to see, unfortunately I don’t have a copy of it at the moment.
