Sam the Eagle
The only voice that I have heard that does not sound very good is Sam the American Eagle. Not that Sam has had some very large speaking rolls lately because he has not but I hope the new crew gets his voice down.
I was reading that Frank is really looking at performing less as a really good thing. the refrence he made was that while Jim was alive the performers were doing a little of everything, running the company, directing, producing and all stops inbetween. After Jim passed the company changed and the crew was able to have a core group of performers who concentrated on just performing, or just directing, or just puppet building, or just directing or what ever.
This gives Frank oppertunity to do other things like direct some big name films which has always been his passion.
