Just a heads up... The UK Blu-ray is an inferior 1080i disc with the PAL speed-up problem - and to compound the insult it also lacks most of the extras found on the US Blu-ray release, like the audio commentary, the outtakes, and "Tucker and Dale ARE Evil" - a 16-minute re-edit of the film from an alternative persepective.
It might be "only" a low-budget indie film, but Tucker and Dale was shot with a Red One HD camera (a serious piece of kit) which only shoots in progressive scan. It does not shoot interlaced. Therefore the UK Blu-ray's 1080i presentation is a deliberate and completely unnecessary downgrading of the source material.
By contrast, the US Blu-ray's 1080p digital-to-digital transfer was described by Blu-ray.com as "a near-perfect Blu-ray presentation."
Why on Earth Sony chose to downgrade the UK disc's transfer to 1080i and drop most of the extras is a mystery only Sony can answer, but it's not something you should encourage with your money.
Needless to say, if you can play the US disc then that's the one to get.
