I have loved this film for many years and to have the widescreen special edition is just great, all previous issues having been 4:3 format. As others have stated, this film just works almost DESPITE itself! By that I mean that that it isn't by any means a great film - the script often leaves much to be desired, and the plot is somewhat simplistic - but for all that it is fantastically entertaining and fun. I would say it is uniquely British and has a charm in the same sense as, for example, the "Carry On" movies. If you like British films in general, and particularly the more "vintage" variety, then you will almost certainly appreciate this. One of those comparatively rare instances when a fims supposed "failings" actually add something almost intangible but nevertheless greatly boost its entertainment value. In my opinion this is British cinema at its most entertaining.
As a footnote to those who do not realise it, the Blue-ray issue also contains an identical issue on DVD, and this is what the "2 disc" reference is about. Somewhat confusing, as no mention is made of this in the product decription on Amazon or for that matter on the front of the disc case! I suspect most people will therefore think that it is simply a Blue-ray release! Very odd marketing!
