Basically all of David Mamet’s films are:
House of Games
The Spanish Prisoner
Glengarry Glen Ross
etc.
So are basically all of Richard Linklater’s:
Slacker
Waking Life
Before Sunrise
Before Sunset
SubUrbia (which is also an Eric Bogosian film, since Linklater directed it and Bogosian wrote it)
etc.
And films made from Bogosian’s scripts are also dialogue-driven, like:
Talk Radio
So are basically all of Whit Stillman’s:
Metropolitan
Barcelona
The Last Days of Disco
So, although not quite as much, are all of Kevin Smith’s:
Clerks
Mallrats
Chasing Amy
Dogma
etc.
Quentin Tarantino’s films are more dialogue-driven than you might expect, given that they’re action films:
Pulp Fiction
Reservoir Dogs
True Romance
etc.
Spike Lee’s are rather dialogue-driven:
She’s Got to Have It
Get on the Bus
Do the Right Thing
School Daze
etc.
So are the films of Noah Baumbach like:
Kicking and Screaming
etc.
But then look at the films of Woody Allen:
Annie Hall
Play It Again, Sam
Husbands and Wives
Shadows and Fog
Broadway Danny Rose
and on and on and on . . .
They’re also sometimes driven by narration, but mostly they consist of talk. I consider directors like Stillman, Baumbach, Smith, Linklater, and maybe even Lee and Tarantino to be “the children of Woody Allen.” They’re all about a generation younger than Allen and presumably grew up seeing Allen’s films. Allen is the reigning master of the film where everyone talks their problems to death.
