Well, the no brainer would a Rodan/War of the Gargantuas two-set. Yes, have the Japanese versions fine, but I would
love to see a restored edition of "Rodan", the U.S. cut. When I was a kid growing up in the 70s, I don't recall that movie having any faded color scenes (or perhaps, I just did not notice it). And yes,
please include the U.S version of WotG!
I would not mind having a three pack of the Toho features released by Brenco Pictures:
The Human Vapor
The Last War
Gorath
(both Japanese & U.S cuts)
And since "The Three Treasures" was mentioned, how about a Mifune/fantasy three-pack?
The Three Treasures
The Lost World of Sinbad (aka Samurai Pirate)
Princess from the Moon, which was shown on TCM not too long ago.
"The Lost World of Sinbad" has a special place in my heart. Though it is not a great movie, it
did introduce me to Mifune (they did
not play any Kurosawa features on the Million Dollar Movie back in the day!).
