Sir Christopher Edward Nolan (born 30 July 1970) is a British and American filmmaker. Known for his Hollywood blockbusters with complex storytelling, Nolan is considered a leading filmmaker of the 21st century. His films have earned over $7.7 billion worldwide, making him the third-highest-grossing film director of all time. Nolan's accolades include two Academy Awards, a Golden Globe Award, and two British Academy Film Awards. He was also appointed a Commander of the British Empire (CBE) in 2019 and was knighted in 2024 for his contributions to film. Nolan developed an interest in filmmaking from a young age. After studying English literature at University College London, he made several short films before his feature film debut with Following (1998). Nolan gained international recognition with his second film, Memento (2000), and transitioned into studio filmmaking with Insomnia (2002). He became a high-profile director with The Dark Knight trilogy (2005–2012) and found further success with The Prestige (2006), Inception (2010), Interstellar (2014) and Dunkirk (2017). After the release of the critically polarising Tenet (2020), Nolan parted ways with longtime distributor Warner Bros. Pictures over their streaming release strategy and signed with Universal Pictures for the highly successful Oppenheimer (2023) and The Odyssey (2026). The former won him Academy Awards for Best Director and Best Picture. Three of Nolan's films have been inducted into the United States National Film Registry. Additionally, two of his films are among the highest-grossing of all time. Infused with a metaphysical outlook, his works thematise epistemology, existentialism, ethics, the construction of time and the malleable nature of memory and personal identity. They feature mathematically inspired images and concepts, unconventional narrative structures, practical special effects, experimental soundscapes, large-format film photography and materialistic perspectives. His enthusiasm for the use and preservation of analogue and IMAX film cameras in cinema production, as opposed to digital, has also garnered significant attention. He has co-written several of his films with his brother, Jonathan, and runs the production company Syncopy Inc. with his wife, Emma Thomas. Nolan has been president of the Directors Guild of America since 2025.
