Inland Empire is the only noteworthy release in the U.K. next week. According to the blurb, the extra features are very different to the U.S. release.

Disc 1: Main Feature
1.85:1 Anamorphic Widescreen
English DD5.1 Surround & DD2.0 Stereo
English subtitles
Trailer

Disc 2: Extra Features
Guardian interview at the NFT with David Lynch (17:23mins)
A Short Interview in London (6:02mins)
A Conversation with David Lynch by Mike Figgis (19:02mins)
A Masterclass with David Lynch (26:14mins)
Interview at the Cartier Foundation (14:59mins)

The U.S. release looks far superior in my opinion, especially David Lynch cooks Quinoa . I think it would definitely be worth importing rather than buying the rather staid sounding U.K. release. A three disc release containing both sets of extras would be good though. 

Cheers Trev.
