For anyone wondering what Soyuzmultfilm is up to, they've been working on this thing (on and off) since 2001. Directed by Stanislav Sokolov. Puppets designed by Mikhail Shemyakin. More information over here: http://en.wikipedia.org/wiki/Gofmaniada
The first 20 minutes were already finished in 2006. I can't quite understand if, according to the video, they spent the past year making a further 30 minutes, or if that includes those 20 minutes from 4 years ago. News report by RIA Novosti.
The newest report says that the final film will be released in May 2014 and be 90 minutes long.
