[Monterey Jack]

Name omnipresent movie clichés which don't really hold up to historical scrutiny, like...

The Black Guy Always Dies First

Film Noir Soundtracks Are Jazzy

Any time a movie is a knowing throwback to/parody of film noir or detective movies from the 1940s, the soundtrack is always awash in lush, raspy sax/trumpet solos (especially when an alluring femme fatale is present), and yet when you watch an actual noir movie from the decade, the scores never sound like this. Actual noir soundtracks were full of terse, dark chords and phrases, yet almost never sounded romantic or jazzy.
