As far as the film goes, I don't think it needs an introduction from me; there are plenty of reviews for that elsewhere. All I will say is that if you are not familiar with it, this is a psychedelic comedy/fantasy heavily larded with classic Beatles songs and some truly iconic animation work that dates very well indeed. I never had the privilege of seeing the remastered dvd edition of this film, but as regards the blu ray I can honestly say it is outstanding. The colours are incredible, far brighter than I remember on my first viewing of the film (and I watched this at the cinema as a child). The painstaking restoration has paid off and this is a work of art.
The sound quality was not quite as much improved, I think, but I don't have a 5.1 system and can only say what it sounded like on a standard stereo set-up. On that basis, it was better than my old videotape by far, but on some tracks could have been improved - there was a noticeable variation in quality. The dialogue, on the other hand, was crisper and clearer than before.
The edition comes in a card slipcase which is nicely decorated with images of the Fab Four from the movie and the interior of the Yellow Submarine, but for something I want to treasure as much as this, I would have preferred a hard case. It includes a nice booklet with lots of illustrations, four film cells and some cute stickers. The extras are an audio commentary by John Coates and Heinz Edelmann; the Mod Odyssey featurette on the making of the film; the original theatrical trailer; three storyboarded sequences, including two never used; original pencil drawings, behind the scenes photos, and interviews with the crew and vocal performers. It claims to be All Region. Sound comes in PCM Stereo, Original Mono, 5.1 in English, German and Italian. Subtitles in English, German, Dutch, Finnish, Italian, Spanish, Portuguese, Swedish, Danish, Norwegian, Finnish and Polish.
