Can’t believe I left out one of my very favorite artists, film-score-or-otherwise:
Henry Mancini.
It ain’t just “Breakfast at Tiffany’s” (though a rightfully mentioned score in this thread already)
“Experiment in Terror,” “Hatari!,” (featuring not only the absolutely brilliant main theme but also the immortal “Baby Elephant Walk”) “Days of Wine and Roses,” “Charade,” “The Pink Panther,” “A Shot in the Dark,” “Dear Heart,” “Moment to Moment,” “Two for the Road,” and “Wait Until Dark.”
