- Adaptation Displacement: The film is much better known than the original play. It's not particularly surprising given the differences in the medium, the All-Star Cast, and the general improvements David Mamet made in the film.
- Crosses the Line Twice: The constant berating is nothing if not unique, which makes some of the insults stinging and hilarious, such as Roma's disdain for an Indian client as he states that he was so stubborn, not even the Indian gods could get him to sign a deal.
- Harsher in Hindsight: "You don't say anything until you know where you are in the story." Kevin Spacey also should have heeded this advice when he tried to pivot the conversation of his years of alleged sexual harassment and abuse toward his coming out of the closet, much to the disgust of the gay community.
- Ho Yay: Roma's seduction of a customer isn't subtle.
- Jerkass Woobie:
- Shelley "The Machine" Levene. In spite of the way we can see how sleazy he is by his sales tactics, he's such a sad sack with a sob story that we can't help but feel sorry for him.
- Roma and Moss probably also count, since the former gets screwed out of a $6,000 deal thanks to Williamson and the latter gets implicated in the robbery by Levene.
- Magnificent Bastard: Ricky Roma, who artfully manipulates a potential customer while riding his hot streak.
- Memetic Mutation: Blake's scene, partly due to this Cracked article. How effective the scene is at illustrating the article's point is up to the reader.
- Misaimed Fandom: Not only is the film loved by the very salesmen it sets out to destroy, but Blake's scene (which is intended as characterizing pretty much everything wrong with corporate America) is used as a motivational tool in workplaces. Of particular note is a Cracked article (see Memetic Mutation above) where the author pretty much uses the scene to describe how one might become a "better person", when David Mamet has openly said he intended that scene to show what was wrong with rampant capitalism and cutthroat sales tactics. To be fair, David Wong also emphasizes a lot in his article that making money alone doesn't make you a better person and explicitly uses the scene as a metaphor (his point is essentially an Anvilicious "It's not who you are, it's what you do" message), but it's still a misunderstanding of the scene and doesn't mention the overall negative effects it has on the plot.
- One-Scene Wonder: Blake's scene in which he completely berates the office staff for their failure to perform. Especially notable as it's original to the film adaptation.
YMMV / Glengarry Glen Ross
