I just watched The Night Visitor. It's a movie from 1971. Max von Sydow plays an erstwhile farmer whose sister and brother-in-law framed him for murder years earlier. Now he's locked away in an asylum but he figures out a way to get out and back in, and he's got no compunctions about killing people for real now. It's sort of a Vincent Price role, but more physical. If von Sydow did a fraction of his own stunts then wow. Trevor Howard is a police inspector looking into the new murders and the old one. The cast includes Swedish, Danish, and British actors, and there's no real attempt to hide that.
It's all filmed in Sweden, though. Sweden in what appears to be the depths of winter. At one point you can see a bevy of swans swimming off a snowy shore. Wintry Sweden is really quite picturesque. Although I don't think I'd recommend running around everywhere in your skivvies, as von Sydow's character does through most of the movie.
