Is on a handful of London cinemas, I saw it at Odeon >:( Covent Garden still showing there I think ??? if that is any help, definitely one to see on the big screen as a lots of shots are extremely dark, and the sound is very minimal in places also. Think this would make it difficult to watch at home. 
Was not among Lynch's best work in my opinion, but it has some great moments, also stylistically is quite a drastic
departure from previous Lynch movies, was shot of digital cameras + lots of handheld stuff.
Defiantly worth trying to find it somewhere.
