In an interview with The Guardian on August 11, 2007, Ed Harris stated that his biggest disappointment has been "The distribution of Copying Beethoven in the US." He also claimed the most important lesson life has taught him is "Don't let MGM distribute a film you care about."

The film was originally written with Anthony Hopkins in mind, for the role of Ludwig van Beethoven.

Bill Stewart died shortly after its release.
