"This movies is most certainly The Violin Player (Le joueur de violon), 1994."
Caught the latter half of this movie on TV perhaps about 6-8 years ago. It was in French so I could not understand any of the dialog.
However, I distinctly remember this scene from it: at the end there is a man playing a violin and he is on a gondola type boat, slowly floating away under an (arched?) bridge.
Thank you very much!
P.S.: Some other random things I think might be from it: was the guy poor and had to sell his violin? was the guy listening to tape recorder and pretending to play? ...
