No luck I'm afraid. I tried play.com but there was noting, not even a release date and I generally find them to be on the ball so you might be struggling. Have a look on eBay but choose the 'available to UK' option on the search, you might get it from USA.
I remember when Miller's Crossing got a DVD release a while back. Details of a Barton Fink DVD were released at the same time but it appears that was shelved. playusa.com is a good place to get if from, that's where I eventually got it. If you have a multi-region player of course.
I did see a Region 2 on Ebay, but a French release, do you think this would be dubbed or just have subtitles, As i don't speak French, i can't read the item description.
