Christopher Edward Nolan (; born 30 July 1970) is an English filmmaker who holds both British and American citizenship.
Having made his directorial debut with Following (1998), Nolan gained considerable attention for his second feature Memento (2000), for which he received numerous accolades. The acclaim garnered by his independent films gave Nolan the opportunity to make the big-budget thriller Insomnia (2002) and the mystery drama The Prestige (2006). He found further success with The Dark Knight Trilogy (2005–2012), Inception (2010), Interstellar (2014), and Dunkirk (2017). His ten films have grossed over US$4.7 billion worldwide and garnered a total of 34 Oscar nominations and ten wins. Nolan has co-written several of his films with his brother Jonathan, and runs the production company Syncopy Inc. with his wife Emma Thomas.
Nolan's films are typically rooted in epistemological and metaphysical themes, exploring human morality, the construction of time, and the malleable nature of memory and personal identity. His body of work is permeated by materialistic perspectives, nonlinear storytelling, practical special effects, innovative soundscapes, large-format film photography, and analogous relationships between visual language and narrative elements. In addition to his filmmaking, he is an advocate for film preservation and the continued availability of film stock.
