From the back cover of the VHS tape of Silent Mouse:
The true story of the famous carol Silent Night starts in a little town in Austria where a chain of strange events happened on Christmas Eve 1887. In Silent Mouse, Lynn Redgrave reveals a curious story of mice and men told in live action, and remarkable photography with a real mouse.
The film was shot entirely on location in Austria and Czechoslovakia. The music brings together some of Europe's most famous ensembles, choirs and orchestras.
