RORY: Sometimes I will add a dramatic pause to prove a point, undercutting my wpm.
PARIS: Let’s not harbor any Pinteresque fantasies here, Rory.
Paris is referring to playwright Harold Pinter (1930-2008), one of the most influential modern British dramatists, with a career spanning more than 50 years. His best known plays include The Birthday Party (1957), The Homecoming (1964), and The Betrayal (1978), each of which he adpated for the screen. He wrote several other screenplays, and directed or acted in radio, stage, television, and film productions of his own and others’ works. He received over 50 awards and honours, including the Nobel Prize for Literature in 2007.
To say that something is “Pinteresque” means that is characteristic of the dialogue in a Harold Pinter play, which (among other things) contains long, brooding pauses. “The Pinter pause” is considered a trademark of his style.
