Metropolis is a monumental work. On its release in 1925, after sixteen months' filming, it was Germany's most expensive feature film, a canvas for director Fritz Lang's increasingly extravagant ambitions. Lang, inspired by the skyline of New York, created a whole new vision of cities. One of the greatest works of science fiction, the film also tells human stories about love and family. Thomas Elsaesser explores the cultural phenomenon of Metropolis: its different versions (there is no definitive one), its changing meanings, and its role as a database of twentieth-century imagery and ideologies. In his foreword to this special edition, published to celebrate the 20th anniversary of the BFI Film Classics series, Elsaesser discusses the impact of the 27 minutes of 'lost' footage discovered in Buenos Aires in 2008, and incorporated in a restored edition, which premiered in 2010.

This compelling study places 'Back to the Future' in the context of Reaganite America, discusses Robert Zemeckis's film-making technique and its relationship to the 'New New Hollywood', explores the film's attitudes to teen culture of the 1950s and 1980s and its representation of science, atomic power and time travel.

Severine (Catherine Deneuve) is a listless haute bourgeouise wife with a secret afternoon life of prostitution. Her life twists repression and guilt together with uninhibited behaviour, strangled libido with its liberated counterpart. Luis Bunuel was catapulted into cinematic history by his groundbreaking Dali collaboration, Un Chien Andalou, in 1929, but it is Belle de Jour (1967) which inaugurates the extraordinary late phase of his work. It is a film shimmering with reflections on truth, fiction and fantasy, in addition to caustic social insight, as it tells the story of a woman clearing her mind, perhaps, of its ghosts.

A legendary fusion of science fiction and horror, Ridley Scott's Alien (1979) is one of the most enduring films of modern cinema – its famously visceral scenes acting like a traumatic wound we seem compelled to revisit. Tracing the constellation of talents that came together to produce the film, Roger Luckhurst examines its origins as a monster movie script called Star Beast, dismissed by many in Hollywood as B-movie trash, through to its afterlife in numerous sequels, prequels and elaborations. Exploring the ways in which Alien compels us to think about otherness, Luckhurst demonstrates how and why this interstellar slasher movie, this old dark house in space, came to coil itself around our darkest imaginings about the fragility of humanity. This special edition features original cover artwork by Marta Lech.

Sunrise: A Song of Two Humans (1927) is one of the most historically pivotal of all films. The first American film of the celebrated German director F.W. Murnau, Sunrise tells the story of a love triangle between characters named only as The Man, The Wife, and The Woman from the City. Lucy Fischer's compelling study of the film shows how it mediates between German expressionism and American melodrama, the avantgarde and popular film, silent cinema and 'talkies'. A lavish and sumptuous production famous for its vast, specially-constructed sets, and one of the first feature films with a synchronized musical score and sound effects soundtrack, Sunrise was one of early Hollywood's most ambitious undertakings. In her foreword to this new edition, Lucy Fischer considers the film as an abiding classic of world cinema.

Ridley Scott's dystopian classic Blade Runner, an adaptation of Philip K. Dick's novel, Do Androids Dream of Electric Sheep?, combines noir with science fiction to create a groundbreaking cyberpunk vision of urban life in the twenty-first century. With replicants on the run, the rain-drenched Los Angeles which Blade Runner imagines is a city of oppression and enclosure, but a city in which transgression and disorder can always erupt. Graced by stunning sets, lighting, effects, costumes and photography, Blade Runner succeeds brilliantly in depicting a world at once uncannily familiar and startlingly new. In his innovative and nuanced reading, Scott Bukatman details the making of Blade Runner and its steadily improving fortunes following its release in 1982. He situates the film in terms of debates about postmodernism, which have informed much of the criticism devoted to it, but argues that its tensions derive also from the quintessentially twentieth-century, modernist experience of the city – as a space both imprisoning and liberating. In his foreword to this special edition, published to celebrate the 20th anniversary of the BFI Film Classics series, Bukatman suggests that Blade Runner 's visual complexity allows it to translate successfully to the world of high definition and on-demand home cinema. He looks back to the science fiction tradition of the early 1980s, and on to the key changes in the 'final' version of the film in 2007, which risk diminishing the sense of instability created in the original.

Leni Riefenstahl's Olympia (1938) is one of the most controversial films ever made. Capitalising on the success of Triumph of the Will (1935), her propaganda film for the Nazi Party, Riefenstahl secured Hitler's approval for her grandiose plans to film the 1936 Berlin Olympics. The result was a work as notorious for its politics as celebrated for its aesthetic power. This revised edition includes new material on Riefenstahl's film-making career before Olympia and her close relationship with Hitler. Taylor Downing also discusses newly-available evidence on the background to the film's production that conclusively proves that the film was directly commissioned by Hitler and funded through Goebbels's Ministry of Propaganda and not, as Riefenstahl later claimed, commissioned independently from the Nazi state by the Olympic authorities. In writing this edition, Taylor Downing has been given access to a magnificent new restoration of the original version of the film by the International Olympic Committee.

F.W. Murnau's 1922 Nosferatu, the first (albeit unofficial) screen adaptation of Bram Stoker's Dracula, starring Max Schreck as the hollow-eyed, cadaverous vampire, remains a potent and disturbing horror film. Kevin Jackson's study traces Nosferatu's eventful production and reception history, including attempts by Stoker's widow to suppress it.

Thelma & Louise, directed by Ridley Scott and written by Callie Khouri, sparked a remarkable public discussion about feminism, violence, and the representation of women in cinema on its release in 1991. Subject to media vilification for its apparent justification of armed robbery and manslaughter, it was a huge hit with audiences composed largely but not exclusively of women who cheered the fugitive central characters played by Susan Sarandon and Geena Davis. Marita Sturken examines Thelma & Louise as one of those rare films that encapsulates the politics of its time. She discusses the film's reworking of the outlaw genre, its reversal of gender roles, and its engagement with the complex relationship of women, guns adn the law. The insights of director Scott, screenwriter Khouri as well as Davis and Sarandon are deployed in an analysis of Thelma & Louise and the controversies it sparked. This is a compelling study of a landmark in 1990s American cinema. In her foreword to this new edition, Sturken looks back on the film's reception at the time of its release, and considers its continuing resonances and topicality in the age of #MeToo.

Spike Lee's Do The Right Thing (1989) is one of the most popular and celebrated examples of the African-American new black film wave. Set during the hottest day of a hot summer in New York City, the film's ensemble cast, including Lee himself, brilliantly play out the edgy negotiations and dramas of a racially and culturally diverse working-class Brooklyn neighborhood. Contrary to Hollywood's markedly cautious treatment of 'race' and its confinement to the South and the past, Do The Right Thing offers a nuanced portrayal of black urban life.From hip-hop fashions, Afrocentric colors and rap music, to police brutality, gentrification, non-white immigration, de-industrialization and joblessness, Do The Right Thing depicts it all, from a contemporary, African-American point of view. In his insightful study of the film, Ed Guerrero discusses how it epitomizes Spike Lee's powerful impact on the representation of race and difference in America, the progress of black film-making and the rise of multicultural voices in the media. This new edition includes a foreword by the author reflecting on Lee's subsequent film-making career and on an America in which African-Americans still contend with racial discrimination and police brutality. Guerrero emphasizes Lee's especially timely understanding of black film-making as a complex act, mixing the skills of art, politics, and business in order to fashion a creative practice that confronts institutional discrimination and power relations head on.
