According to this site it's currently on in 7 cinemas although 5 of them are in London. Not sure if Sheffield or Manchester help you out that much.

Not sure that it will go on general release as it is in Tagalog. I did hear Mark Kermode give it a pretty good review today so you never know it could take off. Best keep an eye for the next few weeks and you may be lucky.
