 * The science fiction film Prey for a Miracle, which was inspired by UFO / gods scare caused by the Latter-Day Pantheon in New York City in March and April 1965, was released. It was directed by a newcomer named Anthony Jones. The film's screenplay was based on the book How I Saved the World by Alexander Lullington-Smythe, which was published by Aphrodite Press in 1976 and was "very publicly discredited" in 1978. The veteran science fiction and horror star Peter Cushing played the lead role of "the mysterious government adviser, Doctor Who," a character loosely based on the First Doctor. However, a film critic for the magazine Film in Focus noted that Cushing's "endearingly eccentric professor [was] as fictional as the rest of Prey for a Miracle" as what little was known about the real life "Doctor" suggested that he was "a shadowy, manipulative figure.
