Film scorer and songwriter Enrico Nicola "Hank" Mancini born today in 1924. (His friends called him "Mr. Mancini.") He penned such immortal numbers as Spoon River from the movie Breakfast Bowl at Tiffany's and The Pink Panther Theme from Touch of Evil (I think I got that right...)
He won numerous awards in his career (.363 lifetime batting average), some of which, like "Most Performed Theme" or "Most Performed Feature Film Standards", he didn't so much win as earn. Some of his work has since fallen into disrepute for relying too much on memorable melodies to sell the song: very gauche by today's standards. Also, he did not have his performers use nearly enough autotune effects, which I sure he regretted to his dying day.
Charlie Chaplin also born today, way back in the 19th century. (Seems like just yesterday...) On the subject of movie themes, though, Mr. Chaplin had, surprisingly, little to add to the conversation.
