This piece of cheapo, post war Nazi & 'Nip' bashing must hold some sort of record for the most on screen verbiage before the first spoken line of dialogue in motion picture history.
First we have a scrolling prologue (four screens full) - Followed by an establishing shot of the 'Bureau of Records', followed by a stock footage interior, and a zoom in on a drawer labelled "Case Histories Crimes Against Women", a tilt down to another drawer: "Confidential". A hand pulls open the drawer and starts to flip through the files giving us a chance to read their titles and some of the contents: (three shots showing eleven separate bits of paper to read). The last piece of paper is turned over to reveal a still photo of some women and a German soldier. Lap dissolve to stock footage of somewhere labelled: "Shanghai". Dissolve to yet another on-screen, full-screen message: "In the Final Days of the war...blah blah blah". Cut to another filing drawer, a hand pulls out yet another typewritten card to read: "Crimes against Hospital Nurses Location: Shanghai". Lap dissolve to a sign "University Hospital"... Dear god! I'm loosing the will to live here... Another dissolve to a sign saying "Nurses Quarters", another dissolve to a crucifix. The entire audience spells out 'I N R I' to themselves they are, by now, so used to reading anything that's on the screen.
In all it's four and a half minutes! before anyone says anything meaningful - and then it's to read out a list of the character's names as they step forward one by one. Heaven help us! Not more establishing!
There are seven writers credited with the script on this; I guess none of them had an eraser.
