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.”  (More from Wikipedia)
