- Al Pacino utterly discombobulating Hank Azaria's character (and Hank Azaria himself, as this was an ad-lib) with:
Vincent: 'Cause she's got a...GREAT ASS!! And you've got your head all the way up it!
- The famous coffee scene. Not only is it a Crowning Moment for the movie and cinema in a meta sense (as it's the first time Al Pacino and Robert De Niro ever shared the screen in the same scene in a movie), but also for the characters in the movie; in a film which isn't without its bombastic and grand moments of awesome, it's strangely fitting that its most compelling moment should be a simple, quiet scene where two protagonists share a coffee, have a pleasant conversation and discovering that, despite the fact that they work on polar opposite sides of the law, they're two similar guys who actually kind of like each other.
- People hunt down the eatery just to sit in that booth. Sadly, it closed in 2014.
- The bank robbery sequence. The most believable, most intense cops-and-robbers shootout committed to film. When a real bank robbery in L.A. happened a few years later, nearby citizenry thought someone was filming a Heat sequel.
- What really sold the sequence was the audio, which sounds like no other cinematic gunfight. None of the gunshots were added in post. Instead, the sound was captured live during filming with carefully placed microphones.
- The level of training and realism is so impressive that Chris' mid-firefight reload is often shown to United States Marines as an example of a flawless tactical reload.
- The armored car robbery is also just as much as Crowning Moment of Awesome as it is an Establishing Character Moment for each member of the crew.
- Neil killing Van Zant and Waingro especially how horrible they were.
