Ford I seem to recall a thriller from the late 80s called PAINT IT BLACK that had the fanfare from Torn Curtain as part of it's score. I remember thinking it sounded out of place. Not sure if Herrmann was even credited but could this perhaps be the one you're thinking of?
Amazing that someone got Paint It Black (1989), a pretty obscure film. On IMDB there is the music credit for Fanfare for Torn Curtain. The composer listed is Jurgen Knieper. The most well known actor listed is Martin Landau.
