Ballet music in "Les Misérables" (1995)

[preludium]

There is a movie based on Victor Hugo's "Les Misérables" with Jean-Paul Belmondo:

The music in this film is quite horrible (strings from synthesizers etc.), apart from a piano piece in a ballet scene. I just cannot believe that it was written by the same person who got the credits for the music in this film. The piece rather reminds me of Rachmaninov. In case you don't have the DVD at hand I tried to reconstruct the piece in the midi file attached - as far as I remember it, because I don't have the DVD either. In the 2nd section I can only reconstruct the chord progression (which is weird enough - three unresolved iv - V cadences that descend chromatically), but there should be a lot more going on terms of arpeggios and stuff. The file ends unexpectedly. In the film the pianist just bangs the keys in that place and I don't want the file to cause any heart attacks, so I dropped that.

Does anyone know this piece?
