Movies with the best dialogue

Not necessarily the most catchy or memorable lines... just the tighest, most brilliant and well written dialogue.

The few that come to mind:

Glengarry Glen Ross: Maybe the best dialogue in movie history.
Pulp Fiction
Network
12 Angry Men
No Country for Old Men

 

& coens' movies generally. lebowski & true grit notable ones

just like NCFOM & True Grit were novels adapted into movies with great dialogue, same with the movies adapted from elmore leonard novels - e.g. jackie brown, get shorty, out of sight

relative to other action movies: a major ingredient in the MCU movies' success is their dialogue - superhero & action movies traditionally had brainless dialogue, but the MCU movies usually have dialogue which is funny & adds depth to the characters. DC & the big Chinese studios have not yet worked this out in their attempt to make good 21st century action movies

 

The Social Network
Django Unchained

 

Barton Fink has some of the best dialogue of any Coen Bros movie.

 

he's taken a int-er-est
