Reports say that the recently unearthed print contains at least 25 minutes of footage thought lost since the severe 1928 editing of the original release. It has been in the hands of the Museo de Cine in Buenos Aires since 1992, but only this year did the museum's new director discover that this print contained the footage long believed to have been lost forever.
Though the 16mm print is said to be in poor condition, I suspect that the missing sections from it will probably be restored and added to the Murneau Foundation's (owners of the rights) 2002 restoration of the film, the most complete version available until now.
Half a dozen stills from the missing footage have been posted by Zeit Online.
