I do know what you mean, hopefully they will make necessarily adjustments to make sure he remains as expressive as possible.I think the problem is the shape of the beak... it seems just kinda small, and the bottom lip doesn't really move all that much either... so I really think it stifles the movement in that aspect. I mean, Sam's beak was a lot more flexible in other puppets. I like the rest of the look fine, but it seems the beak needs a real adjustment to get the full line of expression back.
This was another great video. Few things are as good as Bohemian Rhapsody, but I'm hoping that sometime they will make another video as long as as it.
If I recall correctly, there is still one more youtube video in the can waiting to be released. It is another Swedish Chef cooking video.
Perhaps they have filmed more videos earlier this year, or its possible that after the Chef video is released, there will be no more for a while since they will be concentrating on the movie.
