Slaughterhouse-Five, or The Children's Crusade: A Duty-Dance with Death (1969) is a satirical novel by Kurt Vonnegut about World War II experiences and journeys through time of Billy Pilgrim, from his time as an American soldier and chaplain's assistant, to postwar and early years. It is generally recognized as Vonnegut's most influential and popular work. A central event is Pilgrim's surviving the Allies' firebombing of Dresden as a prisoner-of-war. This was an event in Vonnegut's own life, and the novel is considered semi-autobiographical.
Slaughterhouse-Five is a 1972 anti-war/ sci fi film based on Kurt Vonnegut's novel of the same name about a writer who tells a story in random order of how he was a soldier in WW2 and was abducted by aliens. The screenplay is by Stephen Geller and the film was directed by George Roy Hill. It stars Michael Sacks, Ron Leibman, and Valerie Perrine, and features Eugene Roche, Sharon Gans, Holly Near, and Perry King. The scenes set in Dresden were filmed in Prague. The other scenes were filmed in Minnesota.
Vonnegut wrote about the film soon after its release, in his preface to Between Time and Timbuktu:
"I love George Roy Hill and Universal Pictures, who made a flawless translation of my novel Slaughterhouse-Five to the silver screen ... I drool and cackle every time I watch that film, because it is so harmonious with what I felt when I wrote the book."
