Hong Kong Trilogy: Preschooled Preoccupied Preposterous (known also by its Chinese title 香港三部曲：開門見山、愚公移山、後悔莫及) is a documentary-fictional hybrid film directed by Christopher Doyle. It's a portrait of Hong Kong told by three generations of real people: “PRESCHOOLED” children, “PREOCCUPIED” young people, and “PREPOSTEROUS” senior citizens.

The film had its world premiere in the "Contemporary World Cinema" section at the 2015 Toronto International Film Festival, where it was described in the Toronto Globe and Mail as a "hybrid of fiction and documentary [which] doesn't use a traditional narrative, but it's not entirely abstract either – it's a contemplative sort of parallel storytelling, one where the elliptical space between fact and fiction combines to make a third creature that is no less true." It was subsequently released in theatres in Hong Kong on 28 September 2015 to mark the one-year anniversary of the Umbrella Movement, and also released in theatres in Germany, Taiwan, Greece, and the United States.

When it was released in theatres in the United States, Film Comment named it "Movie of the Week," and critic Jonathan Romney wrote that the "three linked semi-documentary vignettes about a location close to the director's heart—feels as much a community project as a personal statement. It isn't so much an example of the genre known as the "city symphony"—it's more like a city jam."
