Hi James, I see you've just added Kino's new BD, with this footnote:
- Note it hasn't been confirmed as to the reason the Kino Lorber's German version is 4.5 minutes longer than the Eureka's German version.
The German version on Kino's BD is a later, more complete restoration from 2015. Eureka's Murnau BD set didn't come out until the end of 2016, but when they requested the most recent versions of all its films, they were sent Tartüff's earlier restoration instead. Their box set won't be upgraded, but the film's also going to be released on BD in Germany.
I've been in regular contact with the FWMS for the past few years and am working on collectors' guides for all of Murnau's films.
