There is a film titled "Theremin - An Electronic Odyssey", by Steven M.
Martin.  It is on a laser disk from Orion Home Video and distributed by
by Image Entertainment.  Orion's number is ID3366OR.  The UPC code is
14381-3366-6

I don't know if it is still available, but it is an absolutely fascin-
ating and very complete Leon Theremin and his life.  Regards to all
those Theremin fans out there in MMD Land.
