Christopher Nolan is an English-American film director known for his complex, nonlinear narratives. He is motivated to break conventions and expects audiences to piece together fragmented stories. Many of his films feature characters with psychological issues seeking revenge, and who start as heroes but become antagonists. Nolan relies on techniques like rapid cutting and handheld camerawork to convey realism from a character's perspective. Settings are often modern locations, and music enhances the visuals without distraction.
