It's orginal Spanish title is "Las brujas de Zugarramurdi". A better and frankly more evocative title. This Alex de la Iglesia film is quite the ride. It's full of wonderful strangeness, outré imagery, and may give you a Venus of Willendorf phobia. And it's structure feels oddly like a roleplaying game scenario. A group of disparate characters working together to acquire wealth, moving from strange encounter to strange encounter, and finally facing the boss monster in the end.
Check it out if you don't mind reading subtitles and want to see something odd and different. And there's Carolina Bang too. Reason enough.
