Before going into the details...
according to The Digital Bits, Zorba the Greek and Grapes of Wrath are to be released in the US in June too.
Also, The Poseidon Adventure will be in April as WalMart exclusive.
(Maybe we can expect the general release some time later.)
So perhaps I don't need to write about these titles anymore,
but if only for the sake of comparison,
here are the details of the Japanese releases.

It seems Fox Japan selected some of the special features from
US 2-disc "Cinema Classics Collection" DVD,
but unfortunately not everything.
(But I was surprised it's not movie-only.)
