OST from Gattaca
In the scene where the 12 fingered pianist plays his piece, Uma Thurman says to Ethan Hawke that the piece can only be played with 12 fingers, which is totally false considering it was a Schubert Impromptu, which was written for 10-fingered people. [bad word]  it is but if you listen carefully you will notice notes have been added to the tune meaning that you would have to have an extended 6 fingered hand to reach those notes while playing. the production team did a great job of blending them in.]
