A. A. Hoehling, author of the 1962 book Who Destroyed the Hindenburg?, also about the sabotage theory, sued Mooney along with the film developers for copyright infringement as well as unfair competition. However, Judge Charles M. Metzner dismissed his allegations. Filmed largely in color (with a mock newsreel presented in black-and-white at the beginning of the film), a portion of the film is presented in monochrome, edited between portions of the historical Hindenburg newsreel footage shot on May 6, 1937.
