This is great news! Hopefully the new footage contains some salacious red light district footage that was too hot for 1927!
That might come true! I just read yesterday some prostitute related scenes are in there that were deemed to juicy for US distribution. As I understood it, the only version available until now was the US distribution.
1927 was pre-code movies and some of those were fairly racy for their time. Now I don't recall the when the official US release was, so it could have been released post code which at that time racy scenes would have been cut.
Either way I hope they don't poke around or the release, restored or not I want to see the nearly complete film.
