Harmony Korine (born January 4, 1973) is an American film director, producer, screenwriter, and author. He is best known for writing Kids, and for directing Gummo, Julien Donkey-Boy and Mister Lonely. His film Trash Humpers premiered at Toronto International Film Festival and won the main prize, the DOX Award, at CPH:DOX in November 2009.
Korine's most recent feature film, Spring Breakers, starring Selena Gomez, Vanessa Hudgens, Ashley Benson, and Rachel Korine, shot in Florida in early 2012, and received its world premiere at the 2012 Venice International Film Festival, going on to the Toronto International Film Festival.
For some reason, David Letterman took quite a shining to Harmony Korine, and asked him on his show multiple times. Or until he shoved Meryl Streep backstage, which got him banned for life from returning (according to YouTube comments).
