Revolt in the Stars is a science fiction film screenplay written by Scientology founder and science fiction writer L. Ron Hubbard in 1977. It tells the space opera story of how an evil galactic dictator Xenu massacres many of his subjects by transporting them to Earth and killing them with atomic bombs. L. Ron Hubbard had already presented this story to his followers, as a true account of events that happened 75 million years ago, in a secret level of Scientology scripture called Operating Thetan, Level III. The screenplay was promoted around Hollywood circles in 1979, but attempts at fundraising and obtaining financing fell through and the film was never made. Unofficial copies circulate on the Internet.
