David Mamet is one of the all-time masters of film/stage dialogue. His preference for natural conversation, in which characters often interrupt each other and sentences are left unfinished, has come to be known as “Mamet speak.” He has written fiction, nonfiction, screenplays, and stage plays. He has written and produced. And though his isn’t a household name, he is well respected for his diverse talents.
You’ll recognize a few of Mamet’s works, though they aren’t blockbusters. He received the Pulitzer Prize in Drama for the adult play Glengarry Glen Ross, which waas also a remarkable movie. He also received Oscar nominations for The Verdict (Great American Things, Sept. 18, 2009) and Wag the Dog. Other movies he’s responsible for (as screenwriter) include The Untouchables, Ronin, and Hannibal. He’s also directed a couple of small gems: The Spanish Prisoner and State and Main.
I love this description of Mamet from his biography on FilmMakers.com:
Mamet makes few distinctions between working on the stage and the screen; He believes both involve putting the material on its feet and seeing how it plays. With movies, that’s done in the editing room or sometimes on the set. With plays, it’s done during rehearsals. In neither case does he see himself handicapped by being both the writer and the director. “There are two stages,” Mamet says. “First I write the best script I can and then I put on my director’s hat and say, ‘What am I going to do with this piece of crap?'”
