Good review. I thought the movie could've been funnier, but it's OK. And it, along with Jay Ward's "Fractured Flickers" and some of Ernie Kovacs' work, are interesting forerunners of MST3K.
A couple of questions: First, does this new edition also include an egg salad recipe as an extra? Second, has the original Japanese movie, "Key of Keys", ever been released in the U.S.? I wouldn't mind seeing it and finding out just what the heck they were actually doing.
