One of Our Dinosaurs Is Missing

One of Our Dinosaurs is Missing is a 1975 comedy film set in the early 1920s, about the theft of a dinosaur skeleton from the Natural History Museum. The film was produced by Walt Disney Productions and released by Buena Vista Distribution Company. The title is a parody of the film title One of Our Aircraft Is Missing, in which both Peter Ustinov and Hugh Burden also appeared. The film was based on the 1970 novel The Great Dinosaur Robbery by David Forrest. It was the last work of producer and screenwriter Bill Walsh before his death on January 27, 1975, almost six months before the film's release.
