Thanks for letting us know the Blue Underground BD set is region free, Steel.Like you I want all the extras from both the Arrow & BU editions.I watched the Arrow DVD last night and it looks fantastic, easily the best I've ever seen the film look.You can now clearly see all the make-up FX details in the zombies faces, for example.The only thing I wasn't too keen on were the animations preceding some of the featurettes.Apart from that, it's now one of my very favourite DVD's.
