The BBFC web site lists Granada Ventures' "The Lady Vanishes" as being given a "U" certificate on 27/Jan/2005. Could it be that they've had to resubmit the film for classification because they're planning to issue to excellent transfer that was used in the German "Early Years" box set? I did try emailing Granada, but I didn't get a response
I'm not too sure what the deal is with the recent spate of poor quality UK releases from Waterfall Home Entertainment/GMVS Ltd - surely Granada still own the rights to the films?
