- Asexuality: Word of God may have said that Clyde is supposed to be impotent, but the movie never states so and his entire sexual behaviour comes across much more like this. (For example: Why doesn't he try to please the very frustrated Bonnie in other ways than penetrative sex, if he is sexually attracted to her but just suffers from ED? How come his supposed chronic physical problem just spontaneously resolves itself in the end without comment? Why does he act so very awkward when they first try to have sex, and doesn't give himself more than a few seconds time to react to Bonnie's touch before giving up?) Considering this was made in the 60s and the general expectation of A Man Is Always Eager, it's entirely possible that the writer based Clyde's behaviour on somebody who actually was asexual, but who he thought must be impotent. Or that Word of God actually meant "unwilling to have sex" but didn't have a better word for it, in the same way that asexual women were called "frigid".
Clyde: I might as well tell you right off: I ain’t much of a lover boy. That don’t mean nothing personal about you. I mean… I… I never saw no percentage in it.
- Audience-Coloring Adaptation: Virtually all mainstream knowledge of the historical Bonnie and Clyde is from this film, despite the various liberties it takes with the two. There's been some attempts to make a more historically true film about the pair, but they are at best stuck in Development Hell.
- Award Snub: Losing out on nearly all of the major Oscar categories, despite the recognition it received by (some) critics as an innovator for the cinematic landscape. Additionally, it failed to even earn a nomination for Best Film Editing.
- Critical Dissonance: Despite being such a huge success, most critics were repulsed by the film's violence and romanticization of the titular outlaws. One of the few critics that lauded the film, Pauline Kael, quit the New Republic newspaper when they refused to publish her review.
- Damsel Scrappy: The movie version of Blanche, at least in the estimation of her real-life counterpart—she was quoted as saying that "That movie made me look like a screaming horse's ass."
- Freud Was Right: Clyde's impotence is represented by the toothpick in his mouth.
- Hilarious in Hindsight: With all due respect to Splendor in the Grass, the role of the bank robbing Clyde was Warren Beatty's big claim to fame. About three decades later he would take on the role of one of pop culture's most famous fictional lawmen in Dick Tracy.
- Retroactive Recognition: Gene Wilder in his film debut as the male half of the couple that B&C capture.
- Special Effect Failure: Most of the driving scenes feature Obvious Blue Screen.
