sure, you've seen this. possibly you followed through and saw the director's first work as well. if you haven't seen this yet, it contains a few familiar actors and does an excellent job of rounding out what has to be the best unofficial trilogy i've ever seen.
i'd list a few more, but they fail to come to mind at the moment and perhaps imdb is deserving of some harsh words for listing these films under the umbrella of a "UK" country of origin. *glower*
so if you too are enamored with the harsh honesty of scottish cinema, add it to your list of interests (i can't make a link for it until someone else lists it), and respond with any suggestions i haven't mentioned. share the wealth, yo.
