Hi Helen!
I searched all sites I was able to find about the movie. Maybe this site will help you:

It's from davidthewlis.net and they speak about a spanish site dvdgo.its which ships wolrdwide.
Hope I could help you! Greetings from Germany!

Thanks so much for that info. I checked the link and it is region 2 but with Spanish subtitles (I think). Will probably wait in hope that it will be released without subtitles at some point. Alternatively, It would be great if a UK cinema were to screen it. I have a really good independent cinema not far from me so will contact them and see if there's any possibility! Meantime will keep looking!! Cheers!
