|Withnail and I (Blu-ray)||R4|
In terms of Blu-ray comparisons, there is a UK, region free edition released by Starz Home Entertainment in August 2009.
This edition seems very similar to the local Umbrella edition. However, it does also feature the Bruce Robinson Interview (which is also present on the Umbrella 2-disc DVD edition) and The Drinking Game extra, which is absent from all local editions.
All other specs appear to be the same between versions.
