Another current movie which shows an example of mechanical music is
"Miss Potter" starring Renee Zellweger as author-illustrator Beatrix
Potter.  In several scenes, there is a small disc musical box.  The
make of the music box was not visible but collectors may recognize
it.  One scene showed a close-up of the disc turning with the word
"Germany" slowly coming into view.

Although "Miss Potter" is an excellent film, it has not been shown
in many markets.  I had to travel out of town to see the film myself.
If the film is not being shown in your local market, you may have to
wait for it to come out on DVD.
