SO, kind of kidding in my first post, but THRILLED, THRILLED that someone listed The Commitments...AWESOME, and thank you. For some reason (senior moment??) I totally forgot to list it.
I also should have listed The Glenn Miller Story as I am a big band fan, and Help! and A Hard Days's Night (call me Mr. Obvious); Saturday Night Fever (for some of us) is a classic. I realize many hate the BeeGee's and disco, and I get that as I am a soul music fan (1950's and '60's), but whenever SNF comes on, I always listen to the opening. Both film-wise and music wise, this low-budget, throwaway film that was considered kind of a joke became culturally significant. I have to believe it was the music and dancing...the "plot" is kind of thin, right?
Anyway, great film music conductors and those who write and choose the music to accompany the visual have a tough job. Most of the time, they do a pretty good job making the film more enjoyable at the very least, and spectacular when they are at the top of their abilities.
