Rod Serling's UFO film 'It Has Begun'.

More info (and a great pdf article) about Emenegger's film and the subsequent Pentagon involvement in production:

There was more comprehensive, high-level cooperation from the DoD for the production of one particularly unusual film, though – the documentary, UFOs: Past, Present and Future (1974), which considered the extra-terrestrial hypothesis in a much more serious light. The film’s director, Robert Emenegger, was given unprecedented access to DoD facilities, including the highly sensitive Holloman Air Force Base and the Pentagon itself. “The Secretary of the Air Force [Robert Seamans] gave the order to co-operate,” explained the director, who was granted time with highranking military officers apparently well-versed in UFO-related matters, among them Colonel William Coleman, a former spokesman for Project Blue Book, and Colonel George Weinbrenner, then head of Foreign Technology at Wright Patterson Air Force Base.

The film even included a detailed reconstruction of what Emenegger claims the USAF told him was a real extraterrestrial landing at Holloman Air Force Base in 1971, complete with artistic renderings of the alleged aliens.

The USAF even provided Emenegger with a few seconds of footage showing what appeared to be an unusual, bright object descending slowly and vertically over the base. These frames, Emenegger claims, were taken from the “genuine” alien landing footage and officially authorised for use in his completed documentary, which, in line with a 49th Parallel, Vol. 25 (Spring 2011) Graham & Alford ISSN: 1753-5794 (online) 14 recommendation by the USAF, presented the incident as “one that might happen in the future – or perhaps could have happened already.”74 Emenegger claims that he was approached by the USAF to initiate this project, which would be in line with his scholarly interest in propaganda, his history as a Vice President at Grey Advertising, and his personal involvement in the Nixon Campaign to Re-Elect the President (CREEP).75 The film also received support from the Army, the Navy and NASA, with the latter furnishing Emenegger’s production with previously unreleased photographs of what appeared to be UFOs taken in space by Gemini astronauts..
