What movies are you shocked are not commercially available?
The Keep- A theatrically released Michael Mann film with Tangerine Dream doing the soundtrack so this is not some obscure film, unavailable on home video.
Quintet- Apparenlty released only as part of a box set, the box set itself hard to find. I mean it has Paul Newman in the main role.
Kafka, with Jeremy Irons and Teresa Russell has never been released in North America.
Meet the Feebles. Given Peter Jackson’s current popularity, I would think that his entire oeuvre would be generally available, but no. While technically this movie is available on DVD, the version available in the US is just a digital copy of the VHS tape and looks horrible.
Song of the South
Uh, I am not shocked, but still surprised this hasn’t been released.
Well, to each his own, but The Keep and Meet the Feebles were both not only financial failures but were pretty lousy movies as well. Given their now mega-high profiles I’d bet that both Jackson and Mann wouldn’t care if the original negatives were burned, let alone never released on Blu-ray!
As for Song of the South, well, *Uncle Razmus ain’t done gonna not never see him no home releases of anys kinds, lets alones on dem dar blue-sum rays-sum disc-ums! *Again, Disney may not have burned it, but they’ve locked it in a vault and thrown away the key!
Looking for Mr Goodbar - Diane Keaton gave an amazing performance in a dramatic lead role.
The Cook, The Thief, His Wife, and Her Lover - Was briefly released on DVD but long out of print. Was never released on Blu-Ray. And it’s not just this movie - Criterion or somebody should release a Peter Greenaway Blu-Ray box set: The Cook, The Thief, His Wife, and Her Lover, The Draughtsman’s Contract, Drowning By Numbers, The Belly of an Architect, The Baby of Macon, The Pillow Book, A Zed & Two Noughts, and Prospero’s Books. You want Greenaway’s movies, you have to go searching for imports and out-of-prints.
Odd Man Out - The Third Man and The Fallen Idol are readily available but this Carol Reed thriller seems to have fallen through the cracks. Long out of print on DVD and never released on Blu-Ray.
Peter Greenaway’s a good call - his films are visually outstanding and would be marvellous on blu-ray. I guess there’s not a big enough market for them.
Terminator 1 only recently came out on blu-ray, and the delay was surprising. It was well worth the wait, though.
Oh, come on! MTF is hilarious. Granted, it’s juvenile, gross-out kind of hilarity… 
Didn’t realize the Criterion edition of The Fallen Idol was OOP. Argh.
Porgy and Bess with Dorothy Dandridge, Sydney Poitier, and Sammy Davis, Jr.
I read there’s some crappy prints out, but nothing that does it justice.
