For fellow Holocaust researchers: the outtakes of Claue Lanzmann's interview with former Treblinka staff member Franz Suchomel are now publically available:

Fascinating to realise just how much Lanzmann edited it.

A lecture by Erin McGlothin (https://www.youtube.com/watch?v=ivBXmJ2zdtk) indicates that there are portions of the interview where the audio was salvagable but the video wasn't. Anyone know where to find this?
