- Adaptation Displacement
- Ear Worm: The theme song by Ray Charles (which became a moderate pop hit at the time) and "Foul Owl on the Prowl" (later covered by Norah Jones and her Alternative Country band The Little Willies).
- Jerkass Woobie: Gillespie.
"Now, look. I got no wife. I got no kids. Boy, I got a town that don't want me. And I got an air conditioner that I have to oil myself, and a desk with a busted leg. And on top of that, I got this, uh...place. Now, don't you think that'd drive a man to takin' a few drinks? I'll tell you a secret. Nobody comes here. Never."
- Narm: The fight between Virgil and Endicott's goons is choreographed in such a way that, despite being four on one, all the goons ever do is whap on Virgil's pole with a shovel and take harmless swipes at him. It's more like a schoolyard play fight than anything.
- Suspiciously Similar Song: Norman Jewison wanted the song on the diner jukebox to be "Li'l Red Riding Hood" by Sam The Sham & The Pharoahs, but they couldn't get the rights (licensing pop songs for movies being almost unheard of in 1967), so composer Quincy Jones and lyricists Alan & Marilyn Bergman wrote the new but very similar "Foul Owl on the Prowl" for the diner scene.
