Rather infamous cult label Dark Force is releasing "Was Schulmädchen verschweigen" on Blu-ray!
Although it's part of their 'drive-in' series, they apparently used a 4K master of the original uncut camera negative instead of the usual ragged 35mm print, so expectations are high. Sadly, only the English audio is presented here.
It does however include a second feature, the more family-oriented "Wacky Taxi" from 1972 starring John Astin.
EDIT:
By now it's been confirmed this is actually the US version, meaning it's certainly not uncut nor a scan from the OCN. Many shots have also been cropped to hide nudity.
So although it's a real treat to see Ulrike in full High Definition, it goes to show you can never take the word of a pseudo-wrestler accompanied by a diabetic dressed in a banana suit.
