Embedded narratives and crosscutting between different time frames is a major component of his work, and his films often feature experimental soundscapes and mathematically-inspired images and concepts.
His work explores existential and epistemological themes such as subjective experience, materialism, distortion of memory, human morality, the nature of time, causality, and the construction of personal identity.
Regarded as an auteur and postmodernist,[1][2][3][4][5] Nolan's visual style often emphasises urban settings, men in suits, muted colours, dialogue scenes framed in wide close-up with a shallow depth of field, inserts, and modern locations and architecture.
"[11][12] He has continuously experimented with metafictional elements, temporal shifts, elliptical cutting, solipsistic perspectives, nonlinear storytelling, labyrinthine plots, genre hybridity, and the merging of style and form.
[12][13][14][15][16] Drawing attention to the intrinsically manipulative nature of the medium, Nolan uses narrative and stylistic techniques (notably mise en abyme and recursions) to stimulate the viewer to ask themselves why his films are put together the way they are and why they provoke particular responses.
[19] Some examples include the infinity mirrors created by Ariadne in Inception, and Memento's poster design, inspired by the Droste effect, in which a picture appears within itself.
[25] For example, in Memento the fragmented sequential order of scenes is to put the audience into a similar experience of Leonard's defective ability to create new long-term memories.
"[38] Nolan's work explores existential, ethical, and epistemological themes such as subjective experience, distortion of memory, human morality, the nature of time, causality, and construction of personal identity.
[43] He has completed eleven features, [...] all ticking the boxes of studio entertainment, yet indelibly marked with the kind of personal themes and obsessions that are more traditionally the preserve of the art house: the passage of time, the failures of memory, our quirks of denial and deflection, the intimate clockwork of our interior lives, set against landscapes in which the fault lines of late industrialism meet the fissure points and paradoxes of the information age.
Film critic Tom Shone described Nolan's oeuvre as "epistemological thrillers whose protagonists, gripped by the desire for definitive answers, must negotiate mazy environments in which the truth is always beyond their reach.
"[47] In 2020, Richard Newby of The Hollywood Reporter wrote that Nolan's concept of "balancing scales" has become less focused on the individual and "more innately aware of the communal and global."
"[48] Nolan often grounds his stories in broader societal issues, such as corruption, surveillance, economic inequality and climate change,[49][50] and his characters are usually emotionally disturbed, obsessive, and morally ambiguous, facing the fears and anxieties of loneliness, guilt, jealousy, and greed.
"[54] Writing for The Playlist, Oliver Lyttelton singled out parenthood as a signature theme in Nolan's work, adding: "[T]he director avoids talking about his private life, but fatherhood has been at the emotional heart of almost everything he's made, at least from Batman Begins onwards (previous films, it should be said, pre-dated the birth of his kids).
Alec Price and M. Dawson of Left Field Cinema noted that the existential crisis of conflicted male figures "struggling with the slippery nature of identity" is a prevalent theme in Nolan's films.
[68] Like Memento and The Prestige, Inception uses metaleptic storytelling devices and follows Nolan's "auteur affinity of converting, moreover, converging narrative and cognitive values into and within a fictional story".
[70][71][72] Slovenian philosopher Slavoj Žižek said Nolan's The Dark Knight Rises shows that Hollywood blockbusters can be "precise indicators of the ideological predicaments of our societies".
[73] The Dark Knight trilogy explored themes of chaos, terrorism, escalation of violence, financial manipulation, utilitarianism, mass surveillance, and class conflict.
[77] Theorist Douglas Kellner saw the series as a critical allegory about the Bush–Cheney era, highlighting the theme of government corruption and failure to solve social problems, as well as the cinematic spectacle and iconography related to 9/11.
"[79] The article further argues that Dunkirk echoes the work of absurdist playwrights like Samuel Beckett and the bleak, existential novels of Albert Camus and Jean-Paul Sartre.
[110] Christian Bale, Kenneth Branagh, Michael Caine, Gary Oldman, Cillian Murphy, and Tom Hardy have been frequent collaborators from the mid-2000s to the late 2010s, each appearing in upwards of 3 films.
The director has called Memento a "strange cousin" to Funes the Memorious, and has said, "I think his writing naturally lends itself to a cinematic interpretation because it is all about efficiency and precision, the bare bones of an idea.
"[119] Filmmakers Nolan has cited as influences include: Stanley Kubrick,[120][121] Quay Brothers,[122][123] Michael Mann,[124] Terrence Malick,[121] Orson Welles,[125] Fritz Lang,[126] Nicolas Roeg,[127] Sidney Lumet,[126] David Lean,[128] Ridley Scott,[31] Terry Gilliam,[125] and John Frankenheimer.
[130] Nolan's personal favourite films include Blade Runner (1982), Star Wars (1977), The Man Who Would Be King (1975), Lawrence of Arabia (1962), Chinatown (1974), 2001: A Space Odyssey (1968), Withnail and I (1987), and Chariots of Fire (1981).
[137] Nolan's habit of employing non-linear storylines was particularly influenced by the Graham Swift novel Waterland, which he felt "did incredible things with parallel timelines, and told a story in different dimensions that was extremely coherent".
[31] Inception was partly influenced by Dante's Inferno, Max Ernst's Forest series, and the films Orpheus (1950), La Jetée (1962), On Her Majesty's Secret Service (1969), and Zabriskie Point (1970).
[143] Nolan has also praised the comedies Talladega Nights,[144] The Curse (2023),[145] MacGruber[146] as the blockbusters Watchmen (2009)[147] and the Fast & Furious franchise specially Tokyo Drift.
[152] Seeking to maintain high resolution from an analogue workflow, Nolan has at times edited and created release prints for his films optically rather than though digital processes.
To combat this, Nolan believes the industry needs to focus on improving the theatrical experience with bigger and more beautiful presentation formats that cannot be accessed or reproduced in the home, as well as embracing the new generation of aspiring young innovative filmmakers.
He described cinemas as "the most affordable and democratic of our community gathering places" and urged the United States Congress to include struggling theater chains and their employees in the federal bailout.
[177] In 2018, Nolan, Paul Thomas Anderson and other filmmakers reached out to television manufacturers in an attempt to "try and give directors a voice in how the technical standards of our work can be maintained in the home.
