Brando's career afterward was uneven. He was paid one million dollars a week to play the iconic Colonel Kurtz in 1979's Apocalypse Now. He was supposed to show up slim, fit, and to have read the novel Heart of Darkness, but instead arrived weighing around 220 pounds (100 kg) and had not read the book. As a result, his character was shot mostly in the shadows and most of his dialogue was improvised. After his week was over, director Francis Ford Coppola asked him to stay an extra hour so that he could shoot a close up of Brando saying, "The horror, the horror." Brando agreed for an extra $75,000. After this film his weight began to limit the roles he could play.
