I know that A&M records owned it at one time but who owns it now? Is
it even still standing? Can one get in?
It's my understanding that the studio itself is now owned by members
of the Jim Henson family. The Jim Henson Company (owned and run by
members of Jim's family, after a buyback from German media company
EM.TV & Merchandising AG), including Jim Henson's Creature Shop (an
animatronics design/creation and manufacturing company) utilizes the
physical studio plant (what the exact legal arrangements are, i.e.
lease or rent or ?, I don't know). btw, the Jim Henson Co. licensed
rights to The Muppets characters to the Walt Disney Company a few
years back.
As a privately owned company/business, the studio is not now typically
open to the public.
My personal opinion is that the Henson family is respectful and
appreciative of the history of which they are now custodians.
